SEAir Foldable Foil System is designed to be very simple and non-intrusive. The system does not require modifications to the hull. Hydrofoils can be large to improve stability, especially important for vessels with multiple engines. Hydrofoils are spinning around an axis, fixed on the hull itself. Actuators are used to push, pull and block the system in the required position. When not in use, hydrofoils can be protected from damage and fouling by lifting them from the water.

Hydrofoil design is crucial to the success of getting a boat airborne and keeping it flying safely in a range of sea conditions. SEAir design team expertise provides optimal sizing of the foils, along with the profile and structure. SEAir foiling systems are designed to be safe and predictable. By using engine Trim the boat driver optimises fore and aft stability of the boat.

As each boat is unique no foiling system is ‘plug and play’. If a boat builder wants to add foils onto an existing boat, a study is required to define structure reinforcements and depending on the centre of gravity the optimum location of main hydrofoils. SEAir foiling system design service utilises many years of expertise in foiling power boats and sailing yachts. In partnership with boat builders, SEAir can assist with alterations to existing boats or contribute to the design of new foiling boats from 7 metre to over 30 metre.

SEAir foiling systems are designed to provide a reduction in fuel consumption and shock mitigation, enabling boats and people to travel further at sea in comfort. Professional applications range from high performance tenders and fast passenger transport to specialist military platforms.
