Onboard Systems 25 tonne captive winch

 

Super yacht owners are always looking to push the envelope of mechanical design. Every detail no matter how small must be perfect. Sails must move smoothly and efficiently in extreme conditions and without hesitation at the press of a button. Each item of equipment on board a super yacht must have a purpose, excel at that purpose and be as small and light as possible. With their many years of experience supplying custom hydraulic and handling equipment for the super yacht / sailing industry few companies would know this better than Onboard Systems. This is why when developing their high-end product range specifically designed for sheeting in and out of the sails on a super yacht, Onboard Systems looked for something extra special in the design and manufacture process.

 

When first designing the revolutionary Captive Winch range, Onboard Systems partnered with Axiam to help turn their ground breaking concept into reality. The design incorporated processes, design technology and composite materials from the aerospace industry. This integration of industry technologies allowed for major increases in strength while reducing the overall size and weight of the winch. In addition clever innovations have brought about a major technology shift, a result that achieves both high performance and the aesthetics required in the super yacht industry.

 

The Captive Winch product range is unique for moving away from traditional materials and manufacturing techniques.

 

Axiam was able to provide a complete start to finish solution partnering Onboard Systems every step of the way from 3D modelling, tool design, process design, tool build, manufacture, assembly and assist with testing of the 63 different components through to the dispatch of the fully assembled winch. Through this start to finish involvement it is possible to extensively customise the end product to adapt to the exacting requirements for specific applications. Winches can be made to draw in the exact rope lengths required thus eliminating unnecessary bulk or weight. Standard winches can also be made in the range from 5000Kg up to the very high 25000Kgs static load rating with a mix of carbon, stainless and composite materials creating the greatest strength to weight ratio possible.

 

But the final word on how this all went should go to Rod Taylor, CEO and Owner of Onboard Systems: “It was great to be working with a company that could take my conceptual design ideas and turn them into a 3D model through to the manufactured components and the fully assembled and tested product. There are very few companies that can do this as well as AXIAM does”
