Patented hydrodynamic design relies on shape rather than heavy weight, making it more efficient and easier to handle. Hinged-wing stabilizer operates silently without noisy flapper valves or vanes to keep you awake at night. It actually reduces motion sickness and accidents caused by uncomfortable wind and sea conditions. For use on sailboats, the Rock & Roll may be attached to a "swing out" boom or to a spinnaker pole. Storage/carrying case included with stabilizer.
