Williams SportJet 435

If water skiing is big on your itinerary, you’re going to need a sports tender that delivers big torque – the Williams SportJet 435 is it.

This yacht tender is fitted with a 90hp BRP Rotax engine providing the pulling power you need for fast-action water skiing. If you need to take it up a notch, a more powerful 130hp version is also available.

Carrying eight people, in a seating configuration that allows for easy access, space and comfort, the 4.35 metres long Williams yacht tender epitomises modern luxury.  Williams has a passion for craftsmanship and this really shows in the level of design and finish onboard in the upholstery and mouldings. Check out its sleek modern curves and clean lines.  Seating at the aft comes with an adjustable back rest to create lots of room to spread out and sunbathe. You can also pull-up the footrest for optimum comfort on those longer journeys.  And not forgetting the very convenient under-seat storage for your day’s belongings.

The Williams SportJet 435 model, in common with all jet tenders in the Williams SportJet range, features automatic deflation and inflation, shrinking the height of the bow to help the boat slide easily into any size of yacht garage.

Created to be a perfect fit with yacht of 65 feet (20 metres) and upwards, Williams gives you all the accessories you need to boot.

Immerse yourself in the ultimate relaxed lifestyle with luxurious touches including teak inlay, Bimini, the ambiance of LED deck lights and underwater lighting and the latest Fusion MP3 entertainment system.

Be ready to seek out idyllic islands with practical marine technology and equipment ranging from a Chart Plotter and speed control to platform and towing kits.

As the first name in tender customisation, Williams offers many ways you can personalise your jet tender. Select from distinctive tubing and moulding colours, upholstery, and finishes to build your ideal look.
