Williams DieselJet 625

Discover remote faraway coves aboard the elegant Williams DieselJet 625 tender. Her powerful engine, roomy interior and practical add-on accessories provide the perfect combination to get up to 11 passengers there in comfortable style.

Pull down the throttle of the 195hp Yanmar 4LV engine and feel the pull of this keen yacht tender. With the option to upgrade to 230hp, you have the power and speed to glide the waves with total smoothness.

Spanning 6.32 metres (20ft 8 ins), the boat’s long hull length proves to be a great asset for negotiating rough waters with ease and keeping passengers dry in the process.

Even though this is the biggest of Williams DieselJet tenders, she is a nippy agile performer.  Connected to a reliable powerful pump, her drive train is particularly responsive, helping you negotiate tight high-precision turns with a light easy touch.

As well her sporty credentials, the Williams DieselJet 625 is a tender that certainly looks the part when partnered with your luxury yacht. Streamlined throughout, from her sporty hull to her comfortable seating, she displays an air of elegance. Versatile too, the tender boasts a great range of handy inventive features.

Use the various wooden pads and detachable poles to embark and disembark safely and easily from the boat every time. Fold down the windscreen and the tender slips comfortably into a low-clearance garage.

A swim platform and bathing ladder, help you make the most of the waters around your island destination.  Meanwhile the optional Bimini, sunbathing pad, freshwater shower and LED lighting, allow you to kick back and relax in the comfortable surroundings aboard the boat.

Williams stands for customisation and offers an alluring array of tubing and moulding colours, upholstery, and finishes to create your perfect look.
