The size of the mooring buoy depends on the weight it is required to carry. Determine the total weight of the chain, swivels etc and ad a safety margin of at least 25%.
The total gross buoyancy (equals the volume) of the different buoys can be found from the product specs in this website and from our catalogues and leaflets.
The combined weight of the chain + additional gear should under no circumstances exceed 60% of the total gross buoyancy of the mooring buoy. In waters with strong currents and/or heavy growth of seaweed, algae etc., less buoyancy than 60% should be utilised.
The dimensions of the mooring iron bar and swivel should be chosen in accordance with the size and weight of the boat, weather conditions, the currents and wave height in the area the mooring is intended to be placed.
If in any doubt, ask for professional advise from your local harbour master or mooring experts.
Important: For maximum safety, we recommend that only the lower swivel (under water) is used for mooring of the boat!
