With this mooring, the vessel is tied to a buoy, which is itself attached via a chain or rope (known as a riser) to a weight, or anchors on the fundus (riverbed). The arrangement allows the vessel to move so that it will head into the wind or the tide – whichever is the stronger. Such moorings may be in deep water or drying out, sometimes known as mud berths.
Vessels on swinging & trot moorings must be secured in the following manner
Swinging Moorings Anchor chain shackled on to the ring on top of the buoy with shackle pin moused - please do not use stainless steel wire mousing as this causes corrosion; also a rope preventer secured to the buoy with a round turn and bowline or half hitches and then to another secure point on the vessel.
Fore & Aft Trot Moorings As for swinging berths, but in addition two ropes secured aft. When doubled-up breast lines and springs must be used to the other vessel and adequate fenders shipped. The weight of the craft must be taken by its own lines and not by the bridle.
Link Line On trot berths a link line between the mooring buoys must be provided by the berth holder whenever the vessel is away from the berth. This includes winter periods. The link line should be of adequate size and strength and no longer than the total of the vessels and their mooring ropes so as to maintain the berth in its normal state.
- Additional warps must be left accessibly on board for use in emergencies. Lines should NOT be rove through buoy rings as this causes chafing.
- All covers are to be close fitting. Large spray hoods or similar open covers cause windage and place added strain on the mooring and must be stowed when the vessel is on the mooring.
- All propellers on exposed outboards must be covered by a bucket or basket.
