Product Description
Properties
VECTOR FINS™
Vector Fins™ has a unique patented design that dramatically improves roll reduction while simultaneously reducing yaw and sway motions. Constructed with innovative layered vacuum injected vinyl ester compound covering pre-molded foam makes the Vector Fins™ lighter in weight than other fins on the market.
ANY SPEED
Vector Fins™ is the only top-performing stabilizer system for both cruising and at anchor use. The fins’ concave shape creates multilateral force direction improving the stationary positioning of a vessel while at anchor. The uniqueness of the design also becomes evident while underway as it improves in effectiveness as speed increases. Sea trials have proven that Vector Fins™ are up to 50% more efficient at anchor and capable of reducing the uncomfortable rolling motions of the vessel by up to 95% while cruising.
