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.
The Hull Vane® was invented by Dr. Ir. Pieter van Oossanen and is protected by patents in all major shipbuilding countries. Established by Van Oossanen, a household name in ship optimisation, Hull Vane B.V. is operating as an independent company since 2014.
Four more Hull Vanes have been built and delivered to Shipyard De Hoop. Three of them are for Offshore Patrol Vessels, the other is for a Seismic Support Vessel.read more

We have conducted towing tank tests on two models of motor yachts to quantify the performance of the Hull Vane® concept. Both models were tested with and without the Hull Vane® fitted, and the findings were very similar. The Hull Vane® reduced the running trim and sinkage of the model, both of which led to reductions in the resistance, but these reductions did not account for the total difference in resistance measured on these models, which was up to 19%. The designers’ claim that the Hull Vane® produces a net horizontal force, or thrust, was proven in these tests and is fully justified.

We have tested this high-tech system for a specific ship and found a reduction of power between 2.5 and 10 percent. Optimized for a specific ship and sailing conditions, the Hull Vane® is therefore a promising new concept to reduce fuel consumption.

While participating in a tender for a new patrol boat for the Port of Rotterdam, we contracted Van Oossanen for the naval architecture. Based on the operational profile of the boat, they suggested a Hull Vane to be integrated in the design, which we did. We won the tender on lowest life-cycle costs and minimal wave-making. Later on, model tests at Marin confirmed the CFD calculations: a reduction in fuel consumption of 22 to 25% over the entire useful speed range (10 to 19 knots), and a significant reduction in waves generated by the boat

We installed the Hull Vane on a newbuild 55 m Fast Supply Vessel and did sea trials both with and without Hull Vane in identical conditions. Shaft power measurements showed a reduction in fuel consumption of 10% at 12 knots, which increased gradually to 15% at the maximum speed of 21 knots. The difference in wake was very visible even at low speed. The Hull Vane acts as an iron flattening the wave behind the stern.
