Williams DieselJet 415

Ref: DieselJet 415

Our most compact DieselJet brings the craft, practicality and comfort of the DieselJet range to owners of 75ft yachts for the first time.

But its smaller size doesn’t compromise performance. Powered by a 110HP Yanmar engine, the DieselJet 415 lets you and up to five passengers feel the signature thrill of a Williams Jet tender.

In her compact proportions, the Williams Balearics DieselJet 415 yacht tender encapsulates all of Williams’ iconic features. From her impressive high-quality build, functionality and luxury through to her sheer performance power, this yacht tender has it all.

A gutsy 110hp Yanmar 4JH4 diesel engine provides enough exhilarating thrust to gain a maximum 36 mph (57 kph). Cleanly cutting through the waves,  this rib boat’s unique sporty hull is shaped to make it perform in the true Williams way.  Engineered to be up for the job, whether it’s carrying pretty hefty loads or got a water skier in tow, the Williams DieselJet 415 tender is a practical workhorse that won’t let you down.

Clever space-saving ergonomic design is at play onboard, giving up to five passengers ample room to stretch out and relax. The jet tender’s comfortable upholstered seating is bolstered with leg support and handholds, placed exactly where the passengers need them, for feeling safe and secure. Under seat storage takes care of all practical luggage considerations, while boarding platforms are positioned in all the right places to get on and off the jet tender without any difficulty.

Perfectly sized for yachts up to 75ft long, Williams DieselJet 415 fits easily into the lowest height garages thanks to its foldable windscreen and helm console.

This, like all Williams jet tenders, puts you firmly in control and is always stable due to a centrally placed engine and low-profile tubes.  Its responsive pinpoint precision makes easy work of tight tricky movements within the harbour.

In common with your yacht, the Williams jet tender runs on diesel, so on your cruises you no longer need to carry different fuels.

On top of that, with customisable tube, upholstery and moulding colours and finishes you can go bespoke and style the Williams jet tender your own personal way.
