Superior Hulls (Victoria, Canada) developed advanced flexible fins that improve performance of any existing hull, according to the company. Standard vessels’ hulls benefit from enhanced water lubrication. Fast vessels’ hulls can be lifted with the help of flexible fins and can “fly” on top of the waves' crests or flat water. Better stability has been observed, without skidding or tumbling on water at high speeds.
Without Fins
With Fins
The new fins are called Power-fins, Surf-fins and Fly-fins, depending on the application and the vessel’s speed range. They create aquatic lubrication layers along the hull bottom's wetted surface and also offer a lifting capability. Bow-wave, drag and skin resistance are reduced. Significantly increased performance and improved operating efficiency are experienced. The fins only open when the hull is moving in the water, and are not needed to extend open more then few inches. Superior Hulls intend to introduce its advanced fin technology to naval vessels and recreational boats. The company is seeking interested parties to help develop those markets.
