Stabilisation system for yachts

A client approached Brabant Engineering with a patented concept for an innovative stabilisation system for superyachts starting from 35 metres in length. What makes this system unique is its ability to operate both underway and at zero speed.

Weight reduction without compromising strength and stiffness

Brabant Engineering translated the client’s sketch into a fully operational system on board a 37-metre superyacht. As part of the project, we also aimed to reduce weight while preserving the required structural integrity and stiffness.

The system consists of a main shaft and a trim shaft. The trim shaft adjusts the angle of the fin while sailing, allowing the amount of lift to be regulated. The main shaft then locks the fin mechanically in an extended wing-like position to stabilise the vessel during motion.

The solution

At zero speed, wave motion causes uncontrolled roll movements, a major cause of seasickness. The system counteracts this by letting the fins flap alternately against the roll direction, stabilising the vessel within seconds and keeping it balanced.

The dynamic forces acting on the system, especially under way, are immense. Placing extreme demands on the structure and the dynamic seals.

The entire construction, including the connection to the ship’s frames, was fully analysed according to maritime standards and certified by Lloyd’s Register for vessel insurance.
