Sportjet 435

The Sportjet 435 has inherited all the unique design and engineering principles of the Sportjet range – blistering acceleration, incredible stability and exceptional handling. But that’s not all. It’s also adopted the cleverly-designed social, spacious layout, meaning this extremely impressive tender with a LOA of only 4.35m can seat seven people.

Both the Rotax Ace 90hp and 150hp engines deliver all the performance you’d expect from a Williams, meaning it can effortlessly transform from a watersports powerhouse into a stylish, smooth shoreline transport. And like all our tenders, you can precisely customise it to beautifully complement its 20m+/65ft+ parent yacht.

Build my tender

Amazing to ride in. Even more amazing to drive

The Sportjet combines power with exhilaration and safety, whether you're at the helm enjoying the ride or skiing out the back. It is all thanks to the high-performance jet propulsion system, giving you impressive performance without the risk of exposed props.

Serious power at your command

Extreme sports require extreme torque. The Jet Propulsion System delivers all the way, providing exhilarating power at the flick of the throttle. But when you’ve hung up your boards and skis for the day, it will happily function as a dependable and practical tender.

Performance meets safety

Pin-point handling and blistering acceleration – a combination that makes the Sportjet irresistible. Yet it's also extremely safe, manoeuvring confidently at low speeds, thanks to the highly controllable jet propulsion system that has no exposed moving parts.

More space, more practicality

We’ve packed more space and features into the Sportjet. You get two rear-facing seats and a large aft platform to make it easier to get in and out of the water with your gear. There's a removable ski pole for wakeboarding, and when you want to relax the helm seat hinges forward to create a sunbathing area.

Engineered to the very last detail

You get a cluster of instrumentation to help you helm the Sportjet, as well as a foldable helm and removable steering wheel for lower profile storage. There’s the option to add a VHF radio, chart plotter and a Fusion sound system for listening to your favourite tunes while you’re out on the water.

Reassuringly precise

At high speeds the Sportjet is firmly planted in the water, tracking straight and turning quickly and precisely. Its cornering performance has been likened to a racing car, gripping with massive precision. At low speeds, it’s equally confident at manoeuvring into the tightest of spaces or cruising smoothly with a full complement of passengers.

Supreme Stability

The Sportjet is built for both speed and stability. It’s a point-and-shoot machine that will go wherever you want, fast. However, when you need it for more practical duties, it will happily oblige. Its stable hull and superior buoyancy will look after your passengers as they get in and out, and take them safely to the jetty or on smooth leisurely cruises.
