Silent and sprightly, this carbon-fibre tender weighs not much more than an inflatable.

Built to an exacting standard, the electric drivetrain of the SILENT Tender 400 makes it a boat that lives up to its name. Measuring just 4m, it borrows many of its style cues from SILENT-YACHTS’ 60ft and 80ft electric catamarans. Its carbon lay-up ensures that the hull weighs no more than 90kg, which is similar to the weight of a 4m inflatable, making it an easy lift for most davit systems. Designed to carry six people with ease, the SILENT Tender 400 was conceived as the ultimate tender for the solar-powered SILENT 60 series of yachts, as well as serving as a fun electric runabout-cum-mini sports boat.

SILENT Tender 400

It is a compact sports boat in its own right.

Designed with a central console, the Tender 400 has simple intuitive controls, specifically a throttle, a leather-padded wheel and a display showing speed, heading and depth. The helm seat is flanked by two other seats, and there are two bow seats – all with practical handholds. Boarding is via a step in the lowered bulwarks amidships. Owners are able to choose between various inboard and outboard propulsion options. Inboard power comes via a 20kW electric water jet, offering an extremely low draught – ideal for slipping onto the beach. With the sportier outboard, input power is either 20kW or 30kW, depending on the package selected. The higher-rated motor is capable of propelling the boat at more than 20 knots. Battery capacity comes in either the standard 16kWh lithium battery or an upgraded 20kWh unit for more range. At a 10-knot cruising speed there is a minimum of two hours of power, though this will no doubt drop to less than an hour at full speed. Fast on-board charging can replenish the battery in just 2.5 hours.
