Williams DieselJet 445

Ref: DieselJet 445


Completely redesigned for 2021. An overhauled helm with centrally mounted Raymarine display puts you in complete control. Slash-cut tubes make the ride look and feel even sleeker. And larger bathing platforms and extra grab handles make boarding and bathing a breeze.

And with more storage, new upholstery, and space for another passenger to ride in ultimate comfort, the best diesel tender just got better.

Defining luxury and performance on a smaller scale, the Williams DieselJet 445 is a sophisticated yacht tender. A handy multi-purpose boat for nipping off to the jetty, paradise island shores or letting rip on the waves in thrilling water sports action. Perfectly proportioned for yachts of 82 feet (25 metres) and more, this Williams jet tender carries seven people with ample room for any bags and belongings.

Designed with the finesse of clean modern lines and finished to the highest standard, the look of the Williams DieselJet 445 tender is one of sheer luxury. Well-padded seating and handy grab rails cosset passengers bringing a feeling of comfort and assurance.

This very capable rib boat is fitted with a powerful Yanmar 4JH4 110hp diesel engine and deploys a Williams jet pump to reach up to 40mph (64kph). This, combined with a twin lever throttle and shift control, and user-friendly digital navigation and gauges, makes for responsive and precise handling on the open seas and when performing tight docking.

The Williams DieselJet 445 tender is designed to fit all your practical needs. For instance, it features well positioned step boards and poles to ease you along when getting on and off the boat. Then there’s its windscreen, which when folded, reduces the tender’s height to 1.04m, to fit neatly into any garage. Plus, being fuelled by diesel, just like your yacht, it means you just have one fuel type to buy and take with you.

Being a Williams tender, it also benefits from a range of customisable options. Take your pick of tubing, upholstery, moulding colours and finishes to create your own personalised look.

You can also go on to add a whole host of accessories to build your yacht tender to your exact needs. A fresh water shower, LED lights, underwater lights, shore power connection point and choice of navigation systems are just some of the customised options you have to get maximum pleasure from your yacht tender.
