Once banned from the America’s Cup for providing “an unfair advantage,” a Hull Vane was affixed to a launch from Heesen Yachts to provide enhanced efficiency. The result was unbelievable.


The Hull Vane® is a patented fixed foil located below the stern of a ship, for fuel saving and improved seakeeping. The Hull Vane influences the stern wave pattern and creates hydrodynamic lift, which is partially oriented forward. This results in a reduction in of the ship’s resistance. The performance of the Hull Vane® depends on the ship’s length, speed and hull shape in the aft sections, and ranges from 5 to 15% for suitable ships. In specific cases, savings up to 20% are possible.
