Silent Speed 28

By combining our futuristic design language with blistering pace and a superyacht finish, the Speed 28 is the first of a new breed of SILENT. She is powered by a state-of-the-art eD-TEC drivetrain, including foil assistance and embedded solar cells on the hardtop.

This marks the start of a strategic partnership between the SILENT Group and eD-TEC. Together, this technological alliance will take electric mobility on the water to a new level.

This innovative speedboat is ideally suited as a superyacht tender or as a fun boat that can easily be trailered – a perfect blend of unmatched performance with range and comfort.

Pure adrenalin

The original concept of the new model was developed by eD-TEC. Twin 100kW eD-QDrive electric motors are the heart of this 8.6m rigid inflatable boat. These make it capable of eye-watering speeds in excess of 60 knots for short bursts. The lithium-ion batteries (LiFePO4) storing around 100kWh of energy, allow it to cover more than 70 miles at cruising speed, which is an exhilarating 30 knots.

The  Silent Speed 28 is controlled through an intuitive and custom-designed user interface, which keeps the most vital information and functions always in sight. Three foils significantly increase range and comfort.
In auto mode, the AI box assists the driver’s inputs via the rudders, throttle and foils to create the most efficient cruising experience.

Lightweight and robust

Lightweight and robust

The hull shape closely resembles a catamaran, with two narrow hulls in the water and a broad, blunt bow above the waterline.

Built in carbon fibre, the Silent Speed 28 is lightweight yet remarkably robust. Solar cells generating up to 704W of power cover the upper surface of the hard top, more than enough to maintain the battery that supplies all the onboard systems.
