Williams Jet Tenders Unveiled 3 New Models

Dartmouth, UK, 2025, the company marks its 20th anniversary!

It launches three new models: the SportJet 460, SportJet 520, and the DieselJet 625.

The DieselJet 625 stands out as the largest diesel tender, prioritizing stability and passenger capacity for up to 11 people.

Its robust design and optional self-righting mechanism offer a “grown-up” driving experience with impressive grip, suitable for demanding conditions.

For exhilarating performance, the new SportJet 460 delivers enhanced sociability. It is powered by a Rotax 170 petrol engine.

Its agile handling and quick planing make it “tremendous fun” for watersports.

Topping the SportJet range, the SportJet 520 shares the 460’s hull but boasts a supercharged Rotax 230 engine.

This transforms it into a “fast RIB.” It offers “supremely rapid” acceleration.

The ride is aggressive yet controllable, as you can see in the video.

The Williams Composites Story

Williams ‘By Design’ – Composites Explained

Mark Colbourne, the concert manager at Williams Jet Tenders, details their manufacturing process.

It begins with CNC cutting and proceeds through various coating stages, infusion, bonding, trimming, and finishing.

Mark Colbourne, composite manager, notes a trend towards darker colors in recent years. This trend poses challenges in finishing but also offers opportunities for innovation.

British Built Williams Jet Tenders prioritizes sustainability by incorporating recycled materials like P cores made from soft drink bottles.

They also explore future resin systems for fully recyclable boats. I hope they succeed.

Ofcourse there is already DANU™ that is being used and is fully recyclable. It is done by Ultimate Boats.
