Description Layout Technical specs
Solar electric motor yacht

Developed over the last 4 years to protect our environment. Batteries are charged from solar panels, a back-up generator or directly from the shore power socket.


No greenhouse gas emissions compared with combustion engine yachts.

Full autonomy

The Whisper 50 is based on 2 electric motors connected to shaft lines. The electric motors are fed by 240 kWh battery pack.

Low maintenance costs

90% savings compared with combustion engines. Electric propulsion is very simple and basic in design: it requires no exhaust, no gearbox, no mechanical movements and gives off very little heat.

Innovative design

Volume equivalent to larger monohull motor yachts. Space for comfortable indoor and outdoor living. High stability for guest comfort, eliminating the need for costly outriggers.

Maximum speed

At full speed, the Whisper 50 can reach 15 knots.

Highest requirements

Whisper Yachts has selected the best profile/length/width/draft ratio to optimize the hull's performance in the water with minimal resistance. The aft part of the hull is raised to promote horizontal action of the propellers without compromising on draft.

The materials used in the construction of the hulls and superstructures have received meticulous attention. Whisper Yachts and Berret-Racoupeau Design have chosen the most advanced composite techniques to ensure the perfect balance between comfort and lightweight construction.
