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.
The Hull Vane was invented by Dr. Ir. Pieter van Oossanen and is protected by patents in all major shipbuilding countries.
