2026 Williams Jet Tenders Sportjet 435

The Williams Sportjet 435 is a 14.3-metre composite runabout powered by a single Rotax ACE 1603 jet engine producing 130 horsepower. This model is purpose-built as a tender for larger yachts, with a hull design engineered to deliver responsive handling and good speed for a boat of its class, reaching approximately 43 knots. The compact beam of 6.4 metres makes it practical for davit deployment while maintaining stability across the water.

The boat accommodates up to seven people across its open layout, with comfortable seating and a sports-oriented design. The tubes are finished in Hypalon in off-white and grey, while upholstery is Silvertex Plata. The helm position includes a digital depth sounder, and entertainment comes from a Fusion MP3 music system. Four LED deck lights are installed for visibility during evening operation, and teak trim adds a refined touch to the helm area.

This example comes equipped with the 130-horsepower engine upgrade, which is the configuration most commonly specified for the model despite the standard 90-horsepower option. The jet propulsion system offers the shallow-draft characteristics and maneuverability typical of jet-drive tenders. The boat carries a 36-month manufacturer's warranty from first use.
