A stabilizer fin is the device which develops the hydrodynamic forces needed to
counter the roll motions of the vessel. The fin is installed on the stabilizer hull unit
shaft, which serves as the axis about which the fin is deflected. Much like an airplane
wing, as the fin is deflected, pressure differences result in a hydrodynamic force on
the fin. This resultant force is used to counter-act the roll of the vessel.
Designed based on extensive experience and model testing, the QC1800 S-series
stabilizer fin is capable of significantly reducing vessel roll during underway
