These stylish high power Dieseljets come in five sizes: Williams 415, Williams 445, Williams 505, Williams 565 and Williams 625.
Williams 415 – 6 persons Dieseljet
Designed for yachts with an overall length of 23 meters or more, the most compact of the Dieseljet series is suitable for easily transporting 6 persons or towing a monoskier with a deep water start. The 110 hp Yanmar diesel engine offers enough power and there will be no petrol needed on board. The tender can be refueled directly from the mother yacht.
Her practical deck offers maximum seating with plenty of open space to move around. The Dieseljet 415 is designed to be extremely stable when in rest position, so getting on board is safe and secure. While moving at high speed, the passengers are in the center of the boat, so that they are as comfortable as possible. On the move, a deep sporty hull ensures safe handling and smooth transport over choppy waters.
Designed for yachts with a total length of 24 metres or longer, most compact boats in the Dieseljets series are suitable for easily transporting 7 people or towing a monoskier with a start in deep water. The 110hp Yanmar diesel engine (100HP US model) offers enough power. The tender can be refuelled directly from the mother yacht.
Her practical deck offers maximum seating with enough open space to move around. The Dieseljet 445 is designed to be extremely stable at rest, so getting on board is safe and secure. When travelling at high speed, passengers are positioned in the centre of the boat to ensure they are as comfortable as possible. Along the way, a deep sporty hull ensures safe handling and quiet transport over turbulent waters.
The Dieseljet 505 is a practical tender for passenger transport, for yachts with a total length of more than 30 metres. It offers seating for 8 people in a comfortable and spacious cockpit with storage room in the front of the tender, as well as two practical stowage bags under the rear seat. The 110hp Yanmar diesel engine (100HP US model), coupled to the Williams pump, provides propulsion. This proven drivetrain offers precise manoeuvrability at low speeds but also great torque, allowing the Dieseljet 505 to cruise with minimal noise, even when fully loaded.
As with all models in the range, the Dieseljet 505 can be fitted with a number of practical accessories designed to enhance the boat and provide it with more extensive cruising options. These include a foldable windscreen and bimini top (which can be used on the move, subject to a speed limit) providing full protection in the centre of the boat. An easy single-point lift kit is also available. This is ideal for quick starting and repair or for garage mounted cranes, where height is limited.
The Dieseljet 565 is larger than the 505 both in length and deck size. This not only provides extra hull in the water for better performance in rougher conditions, the deck space has also been improved to provide more storage space and seating for 9 people. It is equipped with a 150hp Yanmar diesel engine (optional: 4BY3 180HP engine) which provides extra power through the Williams pumping system so that the Dieseljet 565, even when fully occupied with passengers, can easily lift itself out of the water.
As with all Dieseljet models, the optional customisation options have been extended. All fibreglass shapes can be colour matched or finished with metallic paint. The colours of the inflatable floats can be chosen from 30 different options and the upholstery can be chosen from vinyl or Sunbrella fabric. In addition, the name of the yacht can be placed on the inflatable floats and embroidered into the upholstery of the backrests. The end result is a tender that reflects the style and taste of the owner and is sure to attract attention in any port or bay.
The Dieseljet 625 is the largest model in the series and offers a spacious open deck for extra seating and storage. Powered by the 220 hp Yanmar diesel engine, the 625 performs its tasks with ease. Her extra hull length increases performance in rough water and allows the boat to cleave effortlessly through the waves, giving the 11 passengers a dry and comfortable ride, even on longer trips from the mother yacht.
Like all Dieseljet models, optional weather protection features, such as a foldable windscreen, spray hood and bimini top, enhance the 625’s practicality as a serious boat for day trips. After a morning waterskiing, guests can use the on-board shower before relaxing in the shade provided by the optional bimini for the 625. A coastal trip at 30 knots is the exciting end to a perfect day.
