This month our @harkenitaly_marine ProCare Team have been pleased to be conducting a full Harken ProCare winch service on @clubswanracing 80 MY SONG.

This is the first hull of the @nautorswan_official Club 80. My Song designed by Náutico Swan and @juank_naval_architecture was constructed with the yards strategic partner @persicomarine.

During this Harken ProCare Level service, all winches are removed from the boat and fully disassembled. They are then cleaned and meticulously inspected by the technical team.

A step-by-step report is compiled as they move through the service procedure. This is completed with the addition of detailed images of all parts. This allows the Harken team to proactively monitor the condition of the equipment and prepare a more personalised and accurate parts replacement and service program for the customer.

The final report can be accessed by the customer through a QR link placed on each winch. The ProCare Dashboard is the customers link to all the technical information regarding the Harken equipment they have onboard the yacht, whether that be Harken winch’s, Hydraulics or Hardware.

The Mark Mills Maxi 72 Balthasar (Previously Alegre) went through some major changes and upgrades this year!

They said goodbye to the Harken pedestals and existing Harken winch system. This system was originally from a 2007 Americas Cup program, utilizing carbon drums & titanium gears. A thorough inspection was carried out, but after 18yrs of hard service, this system did not offer the reliability for a hydraulic conversion.

After meetings with the sailing team, it was decided to utilize 7 x Harken AIR600 winches. The boats program includes Transatlantic & other major ocean races, so having the same winch provides versatility for the sailing team.

The AIR Winch package offered a weight saving over the 1111 / 990 option, & due to its large drum diameter, & customizable gear ratios, it’s Harken’s most efficient winch when comparing line speed vs oil consumption.

This winch system upgrade and optimization took place at the Victory Challenge Base in Valencia and was carried out by our ProCare Authorised Palma Agent, Winch Works.

Firstly, a performance analysis was carried out to look at the expected performance from the proposed system and to fine tune motor and gear ratio selection. Once confirmed the order was placed but the work did not stop there.

Using the same design files that Harken use for CNC manufacturing, 3D printed winch bases were produced, allowing Jason and the Team to proactively prepare the boat for the final installation once the winches were delivered.

5 of the winches are mounted in pods, with limited to no access from down below, so the winches are installed from above deck with motors & hydraulic hoses attached. This required the design & manufacture of custom sealing plates. The plates are sealed with O-rings to allow for easier removal & maintenance.

A mid refit visit was undertaken to ensure optimal alignment of the winches & to test the installation / removal procedures.

Following the installation, testing & sea trials, Harken ProCare where alongside the Balthasar Team supporting them for their first regatta. Following sailing Piers Tyler (Harken ProCare Authorised UK Agent, Winch Workshop) was onboard carrying out a full inspection on the winch system. During this time, he produced a full photographic report allowing both Balthasar and ProCare Teams to monitor the condition of the equipment.

We are pleased to announce that Piers Tyler of Winch Workshop UK has agreed to join the Harken ProCare Technical Team. We caught up with Piers to find out a little more about him and how we will be working together in the future.

PC: First of all, please tell us a bit about yourself, where do you live, where are you from?

Piers: I’m a Kiwi born in The City of Sails, (Auckland). Been floating around Europe for the last 17 years anywhere between Sweden to Spain and now based in the UK in Lymington which is a sleepy seaside town on the south coast, with my young family.

PC: How many years have you been in the marine business?

Piers: You wouldn’t think it but I just released it has been 20 years. Think back I still can’t believe my first boss gave me a job! I was the youngest skipper at a company called Sail NZ which we match raced IACC 80 with guests on board during the week and then match raced on the weekend at Youth scheme at the RNZS, the fun didn’t stop after that with my second job been with Team New Zealand.

PC: What types of boats and gear have you worked with in that time?

Piers: When I first started it was the IACC 80’s, the old America’s cup boats. Then when I moved north, I join Team Ericsson in the Volvo 70 generation. After working with a few different Volvo 70 teams over that period I also started to work with Vendee Globe teams, which was great fun as the boats started to fly. There is a sprinkle of everything else from ¼ tonners to J- Class, but most of my time is spent in the offshore classes.

PC: What's the story about how you came to be working alongside the Harken ProCare Team?

Piers: Well, I think I am lucky regarding that. Mark Gardner contacted me and invited me to join the team. I have been working as a marine engineer on different projects for a while and have always reached out to Mark and the ProCare team when I needed some advice on Harken Products.

So, it’s a real honour to be asked to join the ranks of such a high-quality group of engineers.

PC: What’s the most rewarding/interesting/enjoyable part of your job?

Piers: That easy when the skipper completes a signal handed nonstop around the world race and he doesn’t open the tool bag.

PC: How did you get interested in sailing?

Piers: My family where all keen sailors, first time I was on the water was 3 weeks old, on the family racer-cruiser. Every spare minute I had was sailing as a kid and it really hasn’t changed, I think it just in the blood.

PC: Please tell us about your sailing experience.

Piers: My sailing is a mix between Racing and testing. I have been around a while now stopped counting miles when I got to 100,000. My most notable win would have been the Sydney to Hobart but have had others in the Tour de France a la voile, Tour of an Arabia, Cowes Week, Mini transit class, Class 40 and so on. I have really enjoyed my years with the IMOCA class most of all, it has been great to be involved with the class as it has change so much with the introduction with the foils and fast forward to now with the newest generation it great to see the development happening so quickly.

PC: What do you sail these days?

Piers: A Lymington Scow around a pond with my kids and a beer in my hand. Other ways I am getting my fix currently, is racing on Tulikettu which is a foiling 52 for the offshore racing and locally out of Lymington with friends on a Thursday night.

PC: What else do you like to do?

Piers: I’m lucky enough to live in the New Forest, so would be walking in the forest in the winter or down at the beach in summer with my kids. The rare moments that I’m not been a dad or out racing boats will be found on my motorbike.

PC: Many thanks for your time.

Piers: No worries.

"Piers has vast experience in the industry and has worked with many high profile Teams over the Years. He has great engineering skills and has a meticulous attention to detail. Its a real bonus to have his knowledge and experience as a addition to the Harken ProCare Team.

We welcome Piers to Harken ProCare and very much look forward to working more together in the future".

A brand new Captive Winch is coming. By working together with the best teams in the world, our engineers have developed a product with the highest possible performance to weight ratio. The design of Captive Air marks a new level in the class and is focused on reaching the highest possible load to weight ratio while maintaining our proven reliability. Air Captive is specifically focused for use on mainsheet systems and with applications that don’t require a lot of rope storage. But where the main requirements are the reduced size and weight of the unit. A comprehensive design allowed a reduction of components by integrate multiple function in a single parts. This approach in design is particularly noticeable on the integral main frame structure and on the feeder screw.

The Key points of the New Captive Air are:

Compact design

Light weight structure

Self supporting lateral plates, which include fixing holes

The forward line lead reduces load thought the deck structure

Reduced drum diameter allows higher torque and low weight

Simplified structure design without base plate reduces weight

New concept with integrated guide built into feeder screw

Simon Botes (Harken ProCare Europe Manager) and Mark Gardner (Harken ProCare Global Manager) where pleased to welcome Peter Harken and family to our ProCare Palma office last week.

"Its always great to see Peter and his family here in Palma. He has been a real inspiration to me personally over the years. Its been a while since we all caught up in person after the pandemic, so to be able to listen to his stories and share a drink with him again on the dock after racing was a real pleasure".

Mark Gardner

At the core of Zircon performance are industrial ceramic ball bearings. Ceramic is much harder and smoother than steel or composite, so it requires less force to start moving. Why does that matter? Through the line, you feel even the slightest pull which enables you to fine tune a sail shape. In the lightest breeze, you can ease a sheet when others can’t.

The ceramic ball bearings are mounted inside caged races. The cages keep these bearings apart so they don’t bunch up, touch, and stop each other. The result is a very free-running block with less energy lost to friction — in fact, the most efficient small boat block Harken's ever developed.

Give an unrigged Zircon block a strong spin, and it spins for an incredibly long time. Zircon bearings are more than 700% stronger in compression than stainless bearings of the same size. So, they won’t deform if used within the recommended load limits.

More importantly, they don’t absorb as much energy before starting to roll. This becomes evident when you need to ease a sail in very light air. You feel even the slightest fluctuations in sheet load. When used expertly, that means better sail shape and more speed.

40mm Zircon blocks now available. 57 mm blocks available this April.

Check As most Captive Reel winches are by design, hidden away it's not so obvious that they still need general maintenance and regular checks.

Winches must be visually inspected at the beginning and end of every season of sailing or racing.

The key part of the Harken Captive are the fail safes and the safety measures installed. As the Captive isn't in plane site it's very important that all safety measure are working 100% at all times.

The Harken Captive has a number of mechanical, magnetic and optical proximity sensors that are designed to shut off the captive if, for example a line override is detected.

Description goes here Most of us take traveler cars and tracks for granted but the extreme sail trimming and roll stability requirements of AC75s and AC40s required Harken to redevelop its hardware for a whole new performance level.

Balancing a monohull with no keel on a pair of foils that are offset from the yacht’s centerline has been one of the biggest challenges for high performance yacht design in recent years. Understandably, in achieving this the foils themselves have attracted plenty of attention, particularly among commentators and spectators at the last America’s Cup in Auckland 2020-21.

However, as we are now starting to understand there are far more elements involved in keeping a highspeed show on the road, not least the way in which both the power that’s generated by the mainsail and the roll stability control of the boat are achieved through the fine control of the mainsheet. Here, hardware experts Harken have been in the front line of development in an area of deck gear that many of us would normally take for granted: the traveler track and car. And while Harken was also involved in other key areas such as the winches and the self-tacking system for the jib, the mainsheet system was the most challenging area. ‘We worked closely with Emirates Team New Zealand with the development of the AC40,’ explains Mark Wiss, director of global grand prix and custom yacht sales at Harken. ‘This collaboration has led to developments in the deck gear elsewhere too as the new style of sailing develops. For example, the bowsprit is gone and now there’s a self-tacking jib so the basic configuration has changed a fair bit since the first concept for the AC75 was announced.’ The evolution of any new class will always throw up new ideas, layouts and working practices and the deck hardware will adapt to the change. But the AC40 has marked a very different approach. In addition to creating the next generation of America’s Cup machines, the long-term success of the AC40 also depends on being able to make monohull flight easier to achieve in the broader grand prix racing world outside the Cup circle. And for this to happen the speed and accuracy of the mainsheet system is crucial........

When grand prix yachts gather in port it’s an opportunity for skippers and owners to check out the latest innovations on their rivals’ boats, and for crews to compare notes on how well the new stuff actually works. At the bleeding edge of sailing, new technology isn’t always subjected to rigorous physical testing in the controlled conditions of an engineering lab. Only a few companies like Harken have the resources to build full-scale prototypes and design test benches that accurately replicate the complex, dynamic load cycles of a regatta or ocean race. It’s more usual for a new custom cylinder, winch or traveler design to go from finite element analysis to production and straight into sea trials, tentatively at first and then incrementally towards what has been calculated or estimated to be its theoretical maximum working load.

Almost everyone at the sharp end of sailing is well aware that equipment makers’ claims about performance and durability – and the opinions of other sailors – while often useful, should be taken with a pinch of salt unless they are backed up, validated and proven with real-world test data. Dock talk is cheap and broken dreams can be deadly as well as catastrophically expensive. But in the absence of reliable data that would allow skippers and owners to make informed decisions, empty dock talk can sound as good as the truth.

TEST, LEARN, REPEAT - Without data, how can you be certain what you design will deliver. For years we have been building, testing, and improving the analytics facilities in our factories. They are evidence of a commitment to documenting performance almost as old as...Peter.

Today, HarkenLab provides the high-performance peace of mind that lets customers push what we build, to the front. Our facilities are prepared to test at loads beyond anything yet requested. We welcome the next challenge.

The team at SD Boatworks is very excited to be joining the Harken ProCare global network.

They have a long relationship with Harken, from being the first Harken Hydraulics Service Centre on the West Coast, to being Harken Industrial representatives installing and testing ARS track systems. As a Harken dealer they support the full product range from ball bearing blocks to furlers, tracks, winches and more.

SD Boatworks, founded in 2011 by Julie and David Servais, is the leading rig shop for race boats and superyachts on the West Coast. With a focus on quality work and meeting the customer’s deadline every time, they have built their reputation on precision, reliability and consistency. It is this reputation that earned them their Lloyds Register certification as a service supplier for Masts and Rigging as well as Cranes and Lifting Appliances, a must have to work in the world of superyachts.

At SD Boatworks’ facility on Shelter Island, they have a team of experienced riggers with specialty focuses in the different disciplines of rigging. The Sailboat Rigging Team has a focus on mast pulls and service, rig inspections, standing rigging, deck hardware layout and installation, winch service, and custom rope work including running rigging and high load slings and loops. This team handles the high-end racing crowd, from boats like C&C 30’s up through TP52’s, Maxi 72’s and other large ocean racing yachts.

The Superyacht Team has a specialty focus on yachts over 30 meters, on which they regularly conduct annual lifting surveys of the cranes, tracks, lifting and climbing gear, etc. This team is also responsible for all hydraulics service at the shop, engineering and building new tender lifting bridles and performing winch services. The two teams often work hand in hand on larger projects, with each team handling the work load that falls under their specialty discipline. When asked about joining the Harken ProCare team, David Servais said:

“We couldn’t be more excited about this partnership. The Harken ProCare model is based on reliable, quality service with consistency at the forefront. Combining this level of service with a paper trail of service reports and detailed inspection notes, this provides for a level of care that surpasses the industry standard. SD Boatworks has always worked to achieve the highest level of service, and so many of these systems are already a standard practice for us here at our shop. Aligning this to the Harken ProCare standard is a great step forward for us and our customers.”

David also noted that this will be a huge benefit to their entire client base, as the Harken ProCare network allows SD Boatworks unparalleled access to Harken technical support directly at the factory. This will dramatically speed up ordering of custom parts, winch spares, and all high end components that are commonly found on racing yachts and high end custom boats.

The new 25T Captive arrives as a result of the development that Harken has pursued over the past decade in the field of high-power Captives.

It all started with the development of our 100 Ton Test bench and then with the design and production of the 70 Ton captive prototype. This allowed the development of technical, design and material solutions that can now be utilized on our smaller models, such as the 25 Ton unit.

This new 25 Ton Captive will first be used on a 59-meter Mega Yacht project currently in build.

The most important technical feature of the Captive 25 Ton unit, is that it uses two gear motors instead of the traditional single solution. The reduced size of the gearboxes used, in comparison to that which would be needed for the more traditional single motor solution, leads to a much smaller drum diameter. This saves both overall weight and overall dimensions of the unit making for easier installation.

Running two motors separately also allows a wider range of speeds to be provided up to a certain level of load. In fact, one of the two motors is on standby. Beyond a set threshold the second motor will also engage. This minimizes the volume of oil required to be put into circulation within the system to activate the Captive. This is especially evident at high rotations. With half the flow, the same speeds can be achieved. This is obviously at lower loads, however, as at high-speed rotation the unit does not need to deal with major pulls loads.

Another special feature of the 25 Ton (covered by patent) is the feeder support system, i.e. the element that supports the rope deflection pulley onto the drum. This is usually a highly stressed external structure, thus bulky and heavy in this range of working loads. However in the new 25 Ton unit the lateral force on the pulley are discharged directly to the drum, via a roller. Therefore there is no need to add any extra external structure, this again allows us to reduce overall weight and size.

This solution had already been implemented and tested on our 70 Ton prototype however the Captive 25 Ton unit is the first to benefit from it in a series production application.

A lower demand for oil flow also allows yards to substantially simplify the hydraulic system in regards to power unit, valves, etc.

Finally, it is also possible to accessorize the Captive Unit with a sensor system to monitor the load and the positioning of the line.

Harken Tech training run by Harken ProCare European Manager Simon Botes took place in Gdynia Poland last week. It was one of the most anticipated events by our Harken Poland customers.

Thanks to the hospitality of the "I Love Poland" sailing team we were able to run the training onboard their VO70 yacht and provide the practical knowledge to all participants.

The group consisted of professional sailors, riggers as well as several Harken dealers so it was a challenge to deliver the content suitable for each level of knowledge and experience however Harken ProCare managed to meet and exceed our expectations.

Given Simon’s experience with Ocean Race and Superyachts’ servicing, it was a unique occasion for our customers to absorb that knowledge and learn a few helpful tips and tricks that can be use in their daily jobs.

The training consisted of two intensive days and the only feedback we received from our customers was “We want more” so I guess Harken ProCare will have to return to Poland soon!

Sofia Truchanowicz Managing Director - Harken Poland

Harken ProCare Courses are run by Factory Senior Technicians, available to Yacht Crews, Pro-Sailors and Industry Professionals as an introduction to winch and / or hardware maintenance.

Courses are available Onboard or at ProCare Technical facilities, which include, Palma de Mallorca, Newport, Sydney Australia or our winch manufacturing facility in Limido Comasco, Italy. Alternatively we offer courses online via our dedicated training portal

All courses can be flexible and made to suit your specific needs.

Serving the Harken Range of Gearboxes is pretty straight forward. Due to the Oil Filled housing and the magnet to remove any swarf generated the box can go some time without a full rebuild and oil change.

However a proactive service schedule is recommended to keep the box working as efficiently as possible.

A user and maintenance manual is available, this helps signify where each lubricant's should be as well as any fastener thread lock. (See below)

Oil Level should be just over half way up the shaft as you look through the window. Use 75W/90 oil.

KEY POINTS

Always refer to the user manual.

Take a photo of the configuration, this helps remember the disconnect positions etc.

Use blunt seal tools to remove seals to prevent damage.

Lay parts out in the order they are disassembled.

Inspect all bearing services and bearings for wear.

Clean all parts thoroughly to remove any metal swarf.

Add a small amount of oil on all bearings prior to reassembly.

Add a small amount of grease to all O-Rings before reassembly.

Protect seals from damage from the bevel spline when reassembling. This can be done by taping up the spline with electrical tape that can be removed after the spline is passed through the seal.

Transfer parts to "clean" area before reassembling.

Tef-Gel is important between the housing and the bracket to protect against corrosion.

Use strike marks on all fasteners.

Refill with 75W/90 oil, use a small funnel to fill through either the level indicator or magnet port.

Oil fill guide: 44ml for 404 Box - 97ml for 606 Box -150ml for 808 Box

The Fuse Pin (part 4) is designed into the system to protect the self-tailing ring gear assembly from overload and is a consumable part that needs checking. A C-Clip (Part 3) holds the Pinion (Part 1 & 2) in place if the fuse pin blows.

A overload usually occurs when the self-tailing peeler is knocked or if an insufficient number of rope turns are used on the drum. If you notice that the peeler is moving or spinning for example, then this is a sign that the fuse pin needs replacing. You will need to open up the Self-Tailing assembly and replace the pin. How accessible the fuse pin is depends on the winch size so its always best to refer to the User and Maintenance manual.

Please note if the pin has failed then you will also need to remove any remaining pieces from the winch that may course damage. To overcome this Sikaflex can be added to the pin / clip after assembly, this holds any parts in place if the fuse is blown.

Caution must be taken when removing the ST Fasteners to expose the ST Pinion and fuse pin. The fastener must be heated to around 250 Degrees to release the Loctite. To replace the fastener, make sure both the fastener and female thread are clean of dirt and grease. Apply a small amount of Green Loctite 270 and Strike mark the fastener head with a green line to signify that 270 has been applied.

Note: Do not use Green 270 Loctite if the fastener is driven into Carbon fiber.

Key Points:

Proactively check the fuse pin when maintaining your winch.

Remove all parts of the fuse pin.

Use heat to release Green Loctite 270 on ST Fasteners.

Replace with green strike marks.

Always carry new Fuse pins in your onboard spares kit.

The starting point for the design was our 50.3 STP. The aim, a sophisticated, efficient three-speed winch, optimised to cover the needs of the solo sailor.

The main change made was the power ratio for the third speed. This was revised from 50.4 to 55.2 with the aim to make life easier on board the Class 40.

An update Kit will also be available for those who want to upgrade their current 50.3STP.

The New Performa 55.3 will be visible to the public for the first time at the next Salone Nautica in Genoa at the end of September.

KEY POINTS:

Sandblasted aluminum optimum grip.

Increase power in third speed.

Winch Skirt is built into the drum.

Roller bearings reduce friction under load and offer excellent corrosion resistance.

Pins and gears are made of high strength 17-4PH stainless steel.

In 2019 Harken set out to evolve the design of our Megayacht vangs. Our previous generation, known as the G-Style had been developed by Harken in the early 2000’s to help remedy the tendency that more traditional longer span rod systems exhibited. Which was to buckle under high push loading.

The G-Style design has been well-accepted in the market for dual-acting vangs. Harken’s G-Style design effectively combatted buckling by surrounding the rod and completely supporting it to help transfer the push loads to the working tubes.

Today, Harken’s new mega-yacht vang design, adjusts the tube design to create a more streamlined look by better matching the diameter of the working tube with the extension tube. In addition, the new design makes it easier to seal as water now flows away from the seals.

The new design also offers two different ways to determine the vang’s extension position. The first option is a laser position indicator that works inside the tube and reports through the yachts instrument repeaters. The second option is manually read through a visual ruler engraved directly onto the cylinder. Both are designed to help easily repeat the ideal boom height for furling, whether the crew is at mast or helm positions.

As a result of the design evolution, the unit sizing has also been simplified. Units carry a designation of pull load in tons based on the standard superyacht hydraulics system pressure of 250 bar. So, for example the Harken 50T superyacht vang has a 50T pull force at 250 bar. The new Harken line-up includes 25T, 30T, 40T, 50T and 65T units.

Importantly, the new design lends itself to even higher capacities without looking oversized and bulbous. This will soon be required, as the recent size increases of mega yachts shows no sign of slowing. The push load capacity of these vangs can theoretically be as high as the pull load although generally projects have been specifying push loads 40-50% of pull load capacity.

As a subset of this design initiative, Harken has been excited to have collaborated with Southern Spars on two recent projects. In both applications, significant weight has been saved on these vangs by using carbon to replace aluminium within the extension tube. As is the case with each new design initiative, Harken began with intensive testing to determine the best way to integrate carbon with the new design geometry. This testing indicated that a 50T painted carbon version and a 65T clear coated version would achieve the required performance for these projects.

Harken are pleased to be able to supply carbon extension tubes version to any size superyacht vang we offer.

Please contact Harken for more information on this product or to discuss one of your own.

Callum Cecil (ProCare manager - Australasia)

Handing over the batten!

Our main aim at Harken ProCare is to offer a consistent level of technical support and service no matter where the customer is in the world. To do this effectively you need a constancy within the team, a familiar face to welcome you at each stopover.

Its important to us to have the same Project Managers involved to keep the consistency and to build a relationships with each Yacht.

Last month 3 ProCare Senior Technicians travelled to San Diego to run a winch service. The customer was traveling through San Diego on route to the southern hemisphere.

In attendance in San Diego where Mark Gardner (ProCare Global Manager). Simon Botes the ProCare Manager for Europe, who looks after the yacht while in the Mediterranean and Callum Cecil. Callum is our ProCare Manager for Australasia. Callum will be taking over from Simon as the Yachts main contact while the yacht is traveling through to Australia and New Zealand. By doing this we can familiarise Callum with the yacht and hand the batten over.

It also allows the Captain and Crew to meet Callum which helps in starting to build a relationship prior to their visit.

During the 5 day service period, the Team removed, inspected and carried out a full service (including Self Tailors) on all 18 Deck winches. As well as this they helped update the newest member of the Yachts Deck Team with advise of what and how to maintain the equipment between ProCare Services.

The last service on the Yacht was carried out by Simon and ProCare Authorised Agent Winch Works in Spain in December 2021.

While there the Team was also able to ran a full stock check of the yachts spares parts inventory. This information, in collaboration with the service report history allows us to compile a list of recommended spare parts as well as a list of parts to be changed out at the next service. These changeover parts will be placed on order and then separated into kits for each individual winch prior to the next service.

The next ProCare service will be Managed by Callum Cecil in 6 months time.

Gorilla Rigging Road Trip

It was great to work alongside our ProCare Authorised Agent Gorilla Rigging in Savannah Georgia last month.

Two members of the Gorilla Rigging Team where in attendance alongside ProCare European Manager and Project Manager for the yacht Simon Botes. Although away from their main base in Newport Road Island and with very limited facility's on site. The Gorilla Team where fully prepared bringing workshop facility's to the boat in the form of a 40 ft fully kitted out trailer!

During the limited service period, the Team had the following units to inspect and service:

Captive Winches

05 x 16 Ton Harken Captive Winches

03 x 6 Ton Harken Captive Winches

06 x Captive Tensioner Units

Deck Winches

10 x 1235.3 R1 STR SSS

02 x 1335.3 STR SSS

The grip surface of a winch only ever becomes a topic when there’s either too little, or too much grip. Either case is dangerous!. Too much grip & its impossible to ease the sails, & you normally end up destroying your expensive lines, Too little grip & you can’t hang onto the load, & you risk deforming the winch drum!

Depending on the construction of the drum, Too much grip can sometimes be rectified utilising Scotchbrite pads or emery paper, whereas not enough grip means either purchasing new drums, or having your current drums resurfaced.

Stainless Steel Winches

In the case of Harken Superyacht winches, the grip is achieved through a roughening of the drum surface. This roughened surface will degrade with use, especially if you are racing & using technical rope covers. As the surface degrades, you will need to use extra wraps to hold the load. The load will also shift up the winch drum. This is NOT good for the long term health of your winch!

The drum assembly is made up of components parts & a thorough understanding of its construction is necessary to undertake this work. A large hydraulic press will normally be required to dismantle & re-build the drums. Dismantling your drums every couple of years for corrosion inspection/prevention is highly recommended & this should only ever be undertaken by qualified technicians.

Drums are boxed & shipped to the Harken factory in Italy, where the drums have the new grip applied. The drums are then put through a passivation process where free iron particles are chemically removed from the drum. This ensures the drum does not rust & looks good for many years to come. Drums are then shipped back where they’re re-built with all components parts, utilising anti-corrosives & Loctite's.

Harken introduces the CT0, a Small inline tensioner to work alongside the 1.5T and 3T Captive. Hydraulic or Electric 24V options available, the CT0 works in combination with Harken's 1.5 or 3 tonnes of charging and with tops from 12 to 18 mm in diameter.

Harken 1.5 - 3T Captive Reel Winches bring Mega Yacht technology to boats 13.7–18 m (45–60 ft). Robust and compact, these below deck winches keep topsides clear for a clean, uncluttered look. Use for remote line handling: raise / lower halyard, trim / ease mainsheet—all at the touch of a button. A mechanical switch limits the stroke of the feeder to prevent overtravel. A mechanical slack line system stops the drum from turning when there is no load on the line, preventing overrides. All parts connected to electrical circuitry are positioned on the same side for maintenance. The screw bearings and gear transmission are also located on this side for easy inspection. Bearings are self-lubricated. The main gearbox is sealed and lubricated with oil.

The V™ Block is the highest performing, most efficient block Harken has ever offered. Engineers chose extremely strong, extremely lightweight materials to build block components-3D moulded carbon side plates, titanium races, and captive titanium roller bearings. Then they combined the axial and thrust loads into a single bearing set of angled titanium rollers. The result is a 12% decrease in the number of unique components for an incredibly powerful, but simple lightweight block that surpasses any other block we've ever tested in efficiency at high loads, while spinning freely at low loads for smooth easing in light air.

"To eliminate lead times for customers, we decided to transform our highest performing Grand-Prix blocks. Where previously they have always been custom products, now they will be production products available on-the-shelf," says Mark Wiss, Director of New Business Development. "We increased the high-load efficiency and greatly improved low-load release responsiveness. We named it the V block because the angled inner races and sheave surfaces are 'V' shaped."

 They are available in four a number of sizes dedicated to maximum working loads of 1500 kgf, 3000 kgf, 5000 kgf, 6500 kgf. 800 kgf. 12,000kgf, 26,000 kgf, 20,000 kgf

Side plates are available in anodized aluminium or Carbon fiber.

We are pleased to be able to work alongside and support the Skorpios Racing Team in the preparation of the NEW Club Swan 125 for a transatlantic crossing later this month.

Harken ProCare where onsite in Barcelona working along side Nautor Swan Global service to complete a full workshop service of the yachts 7 x Harken 1135.3 1st Reduced and 2 x 990.3 1st Reduced winches. Below is a outline of the process:

Tuesday AM:

The team arrive onsite. To carry out this service firstly all the winch gearing, housings and drums are carefully removed from their bases and placed in individual labelled containers. The winches are rebuild upside down inside their housing, this reduces the chance of any parts moving or being damaged in transport, allowing the team to transport them safely back to the Nautor Swan Global Service facility.

Tuesday PM:

Once within the service facility all winches are stripped down into each individual component. The parts are then separated between metal and plastic parts before the cleaning process begins.

Wednesday:

Once clean and dry they are then meticulously inspected by the ProCare Team for any signs of wear and or damage. A microscope is utilised to assist and to offer a closer look at any possible damage. Tolerance tools are also used to measure wear and deformation. if required gears are then dressed, this process takes off any slight plastic defamation / burring to the top land of each gear tooth and helps prolong its life and the life of the corresponding gear.

A winch system such as this is operating at a very high speed and constantly at the top of its max working load. Because of this is very important to implement a proactive service program to help monitor the condition of the winches.

The next stage is the rebuild, all worn and damaged parts are replaced as well as all pawl springs as standard. The winch is lubricated and reassembled back into the housing, they are then covered to prevent any dirt ingress before being transported back to the yacht.

Thursday AM:

All 9 winches are carefully rebuilt onboard and tested. A ProCare Service sticker is added to each winch housing to indicated the date of the service, the technician that carried out the service as well as providing a QR code that links the crew directly to the full service report.

During the service photos are taken of the condition of each component. This consistency in service allows us to monitor the life span of components. Meaning we can pre-empt part exchange and update spare stock to confirm parts are available as and when required.

Thursday PM:

Job Done!

We were tasked by S/Y Missy to work on a solution to allow easy in-hauling of the headsail without having to run snatch blocks across the deck and aft to the winches. With input from Captain and Crew and from onboard meetings, we started to develop a neat solution that would integrate seamlessly with their existing hardware. A concept drawing was presented for discussion, and after some small adjustments, we arrived at a design that could be 3D printed for final verification onboard. From final approval the drawings move to our custom engineering production department for manufacture. (See "Its a blast" video below)

All machined in-house at our ISO 9001:2015 certified 16,000 square-meter lean-manufacturing facility in the USA.

The final cars were machined from T6061-T6 Aluminium and Hard Lube-anodized for a UV-stable finish - matching the existing hardware.

With safety a considerable concern with highly loaded lines on superyachts; we were able to clear the deck by running the in-hauler from the headsail clew deflecting aft through our custom car and to the winches through a below deck tube. With this lead the weather deck is kept clear from highly loaded line and snatch blocks.

A word from the Captain:

"It was clear from our first couple of regatta’s that we needed something to sort out a sheeting issue for our race setup. After a brief chat with Simon Botes from Harken ProCare Palma we had a good idea of what was needed and a couple of weeks later Harken came back with designs for a custom in-hauler car.

There was never going to be an off the shelf solution to this sheeting problem, so it was great to be able to sit down with Simon and discuss what was needed and how we were going to do it. The In-hauler car looks the part and most importantly, works just as we had intended."

Following our article covering the 1st Speed Reduced Gearing options within the Harken winch range, we have also had some question about the 4th Speed winch and how it is used.

Although the 1st Speed Reduced Gearing is becoming more and more popular there are still applications that the 4th speed winch may work well for you. There are also a number of 4 speed winches on yachts worldwide.

The Harken 4 speed winch takes the standard 3 speed winch and adds a speed slower than 1st but faster than 2nd.

At first glance the 4 speed winch can be slightly confusing to operate, However below we will try and help clear up any confusion:

Harken’s line of stainless steel blocks reflect the traditional beauty of your yacht’s classic lines. Stainless side plates are mirror-polished for durability and unmatched aesthetics.

This week Harken ProCare's Mark Gardner and Simon Botes popped in to see Jason Beaver and the Team at Winch Works Palma.

As you can see busy times as usual in the Winch Works Workshop as they make sure all Yachts and Equipment are ready for the Caribbean Season ahead.

This month we where really happy to be working alongside the Nautor Swan Global Service Team at their base in Badalona Spain.

Simon Botes (ProCare Europe) with the help and support of the NSGS Team carried out a full deck winch Service onboard Swan 115 Highland Fling. This involved the full dismantle and inspection of all deck winches followed by a detailed report.

As well as the main service we also took the opportunity to train the Nautor Team, updating them on ProCare procedures , Ethos and reporting systems.

We very much look forward to working more with Nautor Swan Global Service in the future.

The atmosphere amongst the Teams in Puerto Portals was electric, as it’s been more than 18 months with no 52 Super Series racing. The Teams where ready and there was a definite eagerness to get back out on the water.

Harken have supplied the TP52 fleet since its beginning in 2005, working with these elite competitors to develop our Winch, Hardware and Hydraulic systems. But the relationship does not stop there. As Harken ProCare and our Authorised agent Gorilla Rigging (Hydraulic Support) are on site to offer technical support and backup to Teams during the Super Series events.

The ProCare platform allows us to proactively check the systems to prevent any potential issue. The teams are competing at the highest level which means all systems are working at their absolute limit. To keep systems performing at their best requires a skilled eye. Our day is split up between morning and evening checks. The ProCare Team carry out component monitoring during each event, looking at the condition of the winch, for example taking photography of each gear and logging this in the daily report. This report helps us to predict when parts may need to be changed out to optimise performance. It also allows us to look at increase manufacturing of specific custom components to suit this need if required.

Once the boats are heading back into dock, we are there to meet them. A quick catch up with all Boat Captains produces a possible works list for the evening, this list usually consists of proactively checking components that may have been pushed hardest during the days racing as well as a general system tune up. We work with the Boat Captains to split these checks out between ProCare and the Team allowing us to perform a full system check each night.

No stone can go unturned when you are competing at this level, every second makes a difference and all detail makes a difference!

"The first health check prior to the regatta confirmed the good state of all components and only one deflector ram seal needed changing in the morning of the second training day. Some oil around the mast base to clean up … no time on the water lost. With spares and tools available that was sorted before the sailors had gotten up from breakfast at the hotel. Happy to report a clean bill of health across the fleet on all Harken cylinders, pumps and valves."

The company has been steadily growing relationships with many industry leaders, one the biggest being Harken as both a customer and a vendor.

Harken ProCare has come online in harmony with the expansion of Gorilla Rigging’s operation allowing them to diversify the services offered to their exist client yachts as well as add new clients that are part of the Harken global network. This new facility has a dedicated clean room for winch and hydraulic service to make inspection, service and repair as efficient as possible. This space is divided into hydraulic and winch sections to ensure no cross contamination of parts.

The future state will be to have the capacity to service the fleet of traveling ProCare yachts up and down the East Coast as well as the Caribbean. Allowing the yachts to have a consistent high level of service and support as they cruise and race.

We look forward to sharing more about Gorilla Rigging and their ever expanding partnership with Harken and Harken ProCare.

“It’s a real pleasure to welcome Jim Stone and the Gorilla Rigging Team into the Harken ProCare network.

By expanding our network of ProCare trained Authorised Agents allows us to offer a truly consistent Global support to our Superyacht and Grand Prix customers”.

Mark Gardner (ProCare Global Manager)

Now in the hands of a new owner, North Star has gone through an extensive refit this past winter in Palma. Amongst many optimisations, the decision was made to remove the manually driven pedestal winch system in favour of a fully push-button hydraulic solution.

The new direction from manual to hydraulic required rethinking the winch package completely and necessitated the removal of the now-dated 12-year-old system. With input from the Harken factory engineering team, the specifications were agreed upon. The manually driven system would be replaced with six hydraulically driven Harken winches using the tried and tested route of two Harken 1111.3 as primaries and four Harken 990.3 as Mainsheet and Runner Winches.

“During the recent refit/ modifications of Maxi72 'NorthStar' we chose Harken for replacement Winches and Harken ProCare for installation/servicing.

“During a difficult period worldwide all timescales were met, required customisation was discussed/ designed/ manufactured/ delivered and installed with zero issues.

We couldn't be happier with the collaboration with the Harken and Procare teams.'

Pom Green - Project Manager 'Northstar'

"It was a pleasure to work with the team from NorthStar on this project. Once the winch specification was finalised we supplied on-site assistance and mounting templates so their experienced boat builders could prepare the deck prior to the Winch Package delivery.

The installation itself was done in conjunction with Winch Works, our authorised ProCare agents and installers in Palma, who always do a great job!

The V65 Fleet have now been around the world twice covering over 60k miles and will soon be embarking on their third circumnavigation of the planet! As you can imagine this puts incredible stress and wear on the systems, the only way to keep these systems working perfectly is a full proactive service program.

Harken ProCare have looked after the One Design fleet since they were first lunched in 2014 - 2015. As a result of this we have a full-service History of each yacht taken at each service stopover. This allows us to monitor the condition of all the Harken equipment, easily spot any trends and proactively replace worn parts prior to any issues occurring on the race track.

By utilising the service history and our experience within the fleet we can spotlight possible areas of concern that may require a more detailed examination prior to the next race. If required we can remove parts and send them back to our Italian facility to be 3D Scanned. This allows us to see any distortion in the part that may take it out of design tolerance. This can help indicate if the part may need replacing.

From our historic service reports and our focused inspection in Genova we are able to construct a recommended refit procedure and parts replacement program to bring the one design V65 fleet back to “Like New” condition prior to their next 27,000 mile lap of the globe!

INSIDE THE AC75 PART 1: Ti. CRX TRACK

In summer 2019 the first AC36 test mules started sea trials. These mules while smaller than the eventual AC75s were configured similarly. Foiling monohulls over 25’ were definitely foreign territory. It quickly became apparent that the travellers for these foiling monohulls would be used very differently than any previous America’s Cup boat. Listening to feedback from teams Harken saw opportunity for improvement. These foiling travellers were being adjust very quickly and very frequently. The travellers were seen as more critical than adjusting the mainsheet. The trimmers wanted to keep constant leech tension in the main sail. When the traveller was eased mainsheet load stayed high. Even when eased, there was near maximum working load in the system. There were two areas where teams wanted more than what the current CRX systems were offering. Hardware that was designed win around the world races was showing signs of wear after a few weeks of training sessions. Rollers were having to be replaced more frequently than we had ever seen before. Additionally, the teams were telling us maximum efficiency was of utmost importance even if it came with added mass. A sticky traveller not easing could spell disaster for an AC75.

INSIDE THE AC75 PART 2: THE ROTARY PUMP

Harken currently offers three sizes of multi-speed, pedestal-driven rotary pumps for Grand-Prix race boats 13.7 - 30.5 m (45 - 100'). They deliver oil faster, more efficiently, and with higher shift points than other pumps of comparable sizes. The 10 and 20 cc pumps shift from 1st to 2nd gear both automatically and manually, with automatic shift points determined by the maximum output of the grinders. If fewer crew are grinding, and not enough power is generated to reach the automatic shift point, pumps can be shifted manually—the 20 cc pump by simply reversing the pedestal handles; the 10 cc pump by using a pull-cord attached to a lever. Pumps are made of corrosion-resistant Hard Lube-anodized aluminium, with aluminium, titanium, and stainless steel components. All pumps include a non-return valve on the outlet to prevent backflow.

Harken Gizmos are a growing line of engineered soft-attach terminations and through-deck pieces. They acknowledge riggers’ desires to minimize weight and eliminate as many heavy metal fasteners as possible. Gizmos are not quite a block, not quite a cleat, they exist in-between-defying classification. Harken’s reputation for precision manufacturing assures the Gizmos are precision-sized and fit together perfectly when assembled. Perhaps most importantly, our distribution network guarantees Gizmos are available in the quantities you need—when you need them. Stay tuned, Harken will soon be offering more Gizmo rigging solutions as customers request them!

After 6 years of sailing worldwide, it was time for a well-deserved overhaul for the Harken Captive winches.

The maintenance work took place at the Huisfit shipyard in Zaandam in the Netherlands, where the ship is in the shed for a refit. We had access to a beautiful workplace and were able to complete our work quickly and efficiently. The goal was to complete a consistent service and follow this up with a full report outlining the works carried out and any items that may need to be monitored.

After 6 years of intensive use, the captive winches still looked great. The winches have been completely cleaned, inspected and serviced, consumable parts were replaced where necessary.

It was interesting to see that it was not the use but the winch's location that determined the required level of maintenance. A winch located below deck near the engine's air intake was much more affected by the salt air than the winch on the other side of the engine's air exhaust; this winch was like new.

Despite the Corona crisis, we have worked well with the shipyard personnel and crew of the ship. We want to thank Huisfit and the crew for this great collaboration.
