Hull Vane BV designs and builds four different solutions to improve the performance and seakeeping of ships and boats. These are all based on the application of submerged wings and extensive hydrodynamic expertise. The type of solution depends of the ship’s size and its speed-to-length ratio. The table below can serve as a rough guideline to see which solutions are applicable to your ship.

Custom Hull Vane®

The Hull Vane® is a proven energy saving device for medium-speed displacement vessels. Each Hull Vane® is custom-designed for a ship to achieve the highest level of performance.


  • 100% customised
  • Steel, aluminium or composite
  • Optimal performance

Semi-custom Hull Vane®

Also recreational motor yacht owners are interested in the advantages offered by the Hull Vane®. With the semi-custom Hull Vane® we have established a cost-effective answer for steel-hulled displacement motor yachts in the range of 10 to 20 metres. Through a systematic analysis of dozens of typical motor cruisers, with lengths of 10 to 20m, and a top speed of 12 knots, we developed a tool to predict the optimal Hull Vane® geometry and position for these vessels, without the need for an individual optimisation per yacht. We use standardised components to reduce built costs and installation time.

Dynamic Hull Vane®

For certain customers the seakeeping effect of the Hull Vane® is as important as the energy-saving aspect. In such cases, we can increase the pitch damping effect by providing the Dynamic Hull Vane®. It has all the characteristics and benefits of the static Hull Vane® but can become active at the flick of a switch. By reducing the vertical accelerations onboard, seasickness is reduced and operations on deck are improved, as well as the performance of all systems, which benefit from a more stable platform in waves.

Foil Assist

Do you wish to increase comfort and safety in waves on your high speed boat with the benefit of improved efficiency and more speed? Foil Assist makes this possible. Foil Assist is a partial hydrofoiling application for planing boats. It consists of a small, passive wing, built of solid stainless steel and mounted amidships under the boat’s hull.

The goal is not to go into a “flying mode” but to carry part of the boat’s weight on the foil. By carrying up to 60% of the boat’s weight on the wing at maximum speed, rather than on the waterline, your boat sails lighter, with less spray and less resistance. The pitching motions are significantly reduced, leading to less seasickness, and less slamming.

Foil Assist is available both for the pleasure craft market and the professional boat market, such as pilot boats, fast patrol boats, sea rescue boats and naval interceptors.
