There are two dreams in yachting: the dream of freedom, and the dream of arrival. The GR63 adds a third — the dream of never depending on anything but the sun and the wind. Fully electric catamarans built for autonomy, robustness and silence.

Construction

Hulls and structures in basalt, aramid and carbon composites: lighter and stronger, with titanium deck hardware throughout. The GR63 weighs 31 tonnes lightship, substantially less than comparable vessels.

Safety

Designed to CE Category A for offshore navigation, with certification in progress. Composite construction built to withstand collision with floating objects, and redundant systems throughout.

Autonomy

282 kWh of batteries charged by 11.5 kW of solar and two 6 kW wind turbines, with methanol fuel cells as backup. No diesel aboard: silent, vibration-free cruising, and no fuel costs.

Choices

The GR63 is the proven platform: designed, built and sea-trialled in 2026. The GR80 is a design study exploring the same architecture at a larger scale.

Vision

Electric propulsion is not a compromise on range or comfort. It is a different way of designing a boat — from the energy architecture up.

An eco-responsible and cost-effective cruising experience: no diesel, no fuel bills, no engine noise — energy drawn from the sun and the wind. The GR63 shows that range and comfort need not depend on burning thousands of litres of fuel, and points toward a more sustainable future for yachting.
