Marine Tenders

Williams Performance Tenders are manufacturers of water jet powered yacht tenders based in Oxfordshire. We have been working with Williams for over ten years and in that time we has supplied Williams with four and a half thousand moulding sets.

After an incredibly successful run of its current models, Williams decided the time was right to review their range, invest in new patterns and production tooling and introduce new improved models right across the fleet. Using the customer supplied CAD information in images or step formats mouldCAM check blends, surfaces, radii, flanges and release angles utilising Rhino and Unigraphics software prior to checking machine head access and running verification processes in Vericut.

Machining then starts on the CMS Poseidon 5 axis CNC machine. At 36m long 6m wide and 3m high and with 0.2mm accuracy this is capable of meeting extreme tolerances and limitless shapes and is assurance that the precision parts will have a perfect fit on assembly. On completion of all machining and spraying, each of the tender range patterns were given a customer approved “high gloss” finish, before being inspected, signed off and moved into mould manufacture.

As each of the high quality boat part production moulds are manufactured for the new models, skilled hands quickly produced a “first off” high quality composite part from each. These parts were then transported directly to Williams ready for their engineers to carry out their pre-production boat assembly. Once the “first off” of each new tender had been fully assembled and lake tested at Williams, type approval for further production was given by Williams.

The production of both the approved new boat parts and additional production moulds needed to support the product demand was then raised to meet this level. Production of 20 patterns, 40 mould tools and 5 new models was completed on time, within budget and in 14 weeks.

“We see NORCO as a strategic partner with Williams, as they continue to supply moulding sets into the future and as our product range further grows and diversifies. They are an integral part of the success of Williams Jet Tenders.”
