Mooring buoys

Rotax decided to bring its experience in manufacturing unsinkable floats to the development of a new generation of mooring buoys.


Produced from rotational-moulded polyethylene, the buoys are also filled with expanded polystyrene (EPS) foam in order to guarantee their unsinkability.
Unlike buoys filled with polyurethane foam, EPS foam is composed of closed cells, which cannot fill with water.
Therefore, after being struck by propellers or violent impacts, and even in the case of deliberate vandalism, your ROTAX buoy will never sink.
In addition to its technical advantages, use of EPS foam enables a 100% recyclable buoy.

In the same way as for pontoon floats, the quality of the EPS foam is checked every week using a procedure that measures its water absorption capacity (7-day test).

The range of ROTAX mooring buoys is available in 4 volumes: 40, 64, 120 and 200 L. They are equipped with through-shafts with an interior diameter of 26, 46, 52 or 63 mm, ideal for inserting mooring ropes, chains or rods.
