Turbojet 285

A nimble tender that defies its size, the re-launched Turbojet 285 is designed to easily fit into the tender garage or bathing platform of most 12m to 16m (39ft to 52ft) yachts. It will take you smoothly to the quayside for supplies or a leisurely bite to eat. But open up the throttle and she'll show you a different side. The sports hull and Rotax engine come into their own, carving tight circles or going flat out in secure straight lines for waterskiing bliss.

Build my tender

Cleaner, lightweight engine

Get improved power to weight, torque and fuel efficiency with the BRP Rotax ACE 900 engine. It performs better and is also cleaner, thanks to a catalytic converter, making it one of the cleanest marine engines in the world. All Turbojets come fitted with a power limit switch as standard, so those who are new to high performance jet tenders can learn in a safe environment.

High Performance

Turbojets are known for outperforming almost all comparable craft on the water, whether it is pulling a waterskier, cruising along the coast or whipping in and out of tight corners. With top speeds of up to 48 mph/77 kph, jumping aboard a Turbojet and firing up the engine is a thrill you will never tire of.

Supreme Stability & Handling

Thanks to continued improvements to the hull design, the latest Turbojet sets the standard for supreme handling, from railing high speed corners to coming alongside your yacht at slow speeds, the new Turbojet takes it all in its stride. By utilising a centrally mounted engine and an inflatable tube, which is positioned close to the water, the Turbojet is supremely stable whether static or running at speed. This makes for easy and comfortable passenger boarding and a safe, enjoyable ride at high speed. What’s more, due to the inherent hull buoyancy, the tender will float even without the inflatable tube.

More torque, less maintenance jet pumps

Our purpose-made jet pumps are not only more efficient, they are also incredibly safe, as there are no exposed moving parts. With stainless steel impeller and double-coated pumps, they provide excellent protection against corrosion, giving you long life with minimal maintenance.

Manoeuvrability in all conditions

Get pinpoint accuracy at both high and low speeds. The unique Turbojet hull, control system and jet pump make getting in and out of tight spots an easy task. Drive up to a yacht or handle confined spaces with utmost confidence. At the other end of the scale, you can open up the throttle for superior high-speed straightline tracking and precision controlled turns.

Clear Instrumentation

Have peace of mind with instrumentation to keep you informed of what’s going on above and below the water. As well as standard instruments, you can specify optional extras such as depth sounder, vhf radio and chartplotter. You can even opt to have a removable steering wheel to make storage easier and as an effective anti-theft device.

Sitting comfortably

The latest Turbojet models have new, re-designed upholstery to ensure you get from ship to shore in comfort. A profiled rear helm seat ensures the driver is gripped tightly, allowing you to get the most from the pinpoint handling. Passengers now benefit from leg bolsters, which in conjunction with the Gul Wing, rotating passenger backrests and abundance of hand holds help even the most nervous passenger feel safe onboard.

Easily replaceable tubes

The inflatable tubes on all Williams tenders have been designed to be removed and replaced, quickly and easily. So you can get back on the water with minimal fuss.
