Side-Power’s Vector Fin Stabilizer system is a unique solution to an old problem: Seasickness. With Side-Power stabilizers, you can virtually eliminate that awful feeling of being seasick, whether underway or at anchor. Fin stabilizers is the only system that provides effective stabilization both at anchor and while cruising at planing speeds, and Side-Power stabilizers are about 30% more effective than all others. The curved shape of the Vector fins provides a more effective, more efficient method of stabilizing your boat at any speed, from at anchor or station-holding, to underway at speeds up to 43 knots. They are approximately 50% more efficient than conventional flat fins, and unlike flat fins, the curved Side-Power fins create enough lift to offset drag, resulting in virtually no loss of speed unlike flat fins. Side-Power Vector fins are designed for vessels between 52 and 150 feet.
