Now, your whole family can enjoy boating more comfortably while anchored, drifting, fishing or moored! Magma’s patented hydrodynamic design breakthrough relies on shape rather than heavy weight, making it more efficient and easier to handle. Our proven hinged-wing stabilizer operates silently without noisy flapper valves or vanes to keep you awake at night. So remarkably effective, it actually reduces motion sickness and accidents caused by uncomfortable wind and sea conditions. For use on sailboats, the Rock ‘n Roll may be attached to a “swing out” boom or to a spinniker pole.(See thumbnail). For use on other boats, we recommend the "Rock 'n Roll" Outrigger. Storage/carrying case included with stabilizer.
