Humphree has developed a series of fixed fins that can be bolted to the hull. The bolts have been tested and verified to break off and keep the hull intact to limit the damage to the boat in the event of collision or grounding.
Many waterjet boats experience course keeping problems. This is due to the missing underwater lateral area that helps the vessel to keep its course. An added lateral area is most efficient when installed in the very aft of the hull. Having a wing profile fin gives a corrective force on yaw with minimum resistance.
Install these fixed fins near the stern and experience the difference as they limit the sideways motion (snake wake) of the propulsion thrust.
Fixed Fin Features
With its sleek, streamlined design, the fixed fin is sub-cavitating for boats with operating speeds up to 40 knots.
Combine with the Humphree Interceptors to experience superior control and performance at any speed.
