Hulls, stabilisers, hybrid engines: innovations to watch out for in 2025 in the world of yachting
Ever more powerful and versatile hulls
The shape of the hull remains one of the fundamental pillars of sailing.
In 2025, we will see the emergence of new generations of hulls:
Double step hulls: inspired by offshore racing, they reduce drag and improve performance at sustained speeds.
Staggered hulls offer a better coefficient of lift thanks to the multiplication of stagnation lines, the high-pressure zones located at the entrance to the planing phase.
This configuration reduces drag, enabling higher speeds to be achieved with smaller engines, while improving fuel consumption.
Fast Displacement Hulls: these offer better fuel efficiency and stability at all speeds.
Optimisation using CFD simulation: many shipyards are now using these tools to create more stable and efficient hulls.
CFD (Computational Fluid Dynamics) is used to analyse fluid flow and simulate the hydrodynamic performance of a vessel under different conditions: speed, trim, list or load.
Thanks to these simulations, it is possible to observe the wetted surface, the pressure distribution, the viscous resistance and the current lines.
The results are then analysed to identify areas for optimisation adapted to the boat’s intended use, in order to improve its sailing behaviour and reduce its resistance to water.
Stabilisers: more compact, quieter, more efficient
Onboard comfort has become an essential requirement. In 2025, stabilisers are becoming more widespread and upmarket:
New generation gyroscopes (Seakeeper, Quick…): lighter and more compact, they are also suitable for medium-sized yachts.
Electric stabiliser fins: responsive and silent, they ensure optimum comfort even when at anchor.
Active stabilisation: whether at sea or stationary, these systems contribute to zen-like navigation.

Hybrid and electric propulsion: towards greener yachting
Ecology is gaining ground on the water.
By 2025, hybrid engines will no longer be reserved for large yachts:
Diesel-electric propulsion: for quieter, lower-impact sailing.
100% electric: increasingly common on day boats and tenders.
Hydrogen and e-fuels research: the first initiatives are taking shape.
