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.
Flexible height
Folding helm and windscreen.
The DieselJet’s folding helm and windscreen – as well as its optional single-point lift – lets you reduce the boat’s height, so you can say goodbye to those precariously tight fitments.
Clear instrumentation
We’ve made the DieselJet’s instrumentation clear, simple and elegant – so you always know what’s going on above and below water.
A Raymarine 170 helm display, depth sounders and chart plotters make navigation easier than ever, so you can be supremely confident on the sea.
Always sitting comfortably
The DieselJet’s seating isn’t just comfortable…
It’s leg bolsters and abundance of handholds ensure you feel more secure, so even nervous passengers feel safe onboard.
Manoeuvrability in all conditions
The DieselJet’s unique hull, control system and pump deliver pinpoint accuracy at any speed.
Handle small spaces and delicate manoeuvres with confidence. Or open up the throttle and feel the thrill of straight-line speed and precision turns.
Easy boarding
Stepping aboard couldn’t be easier.
With multiple boarding points, gripped step pads, stainless steel boarding pole and optional LED deck lighting, stepping on and off your tender has never been easier.
Space, stability and control
The DieselJet offers maximum space for comfortable seating and practical storage.
Its centrally mounted engine and inflatable tubes sit lower in the water, so whether you’re taking hairpin turns or serenely boarding at the jetty, the DieselJet is always at your command.
