Heavy Item

Magma The “Rock ’n Roll” Boat Stabiliser

Sup. No.
- +

Now, your whole family can enjoy boating more comfortably while anchored, drifting, fishing or moored!

The patented hydrodynamic design breakthrough relies on shape rather than heavy weight, making it more efficient and easier to handle.

The proven hinged-wing stabiliser 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 & Roll may be attached to a ''swing out'' boom or to a spinnaker pole.
