Pontoon Moorings can be of various types. The boats are tied fore and aft to pontoons. It is common that large pontoons for heavy vessels are ‘piled’ i.e. secured by steel piles driven into the riverbed. To allow for the rise and fall of the tide these piles have to be at least 6-7 metres above the low tide level of the river and they therefore can be quite obtrusive in sensitive locations. Some pontoons are connected to the shore and are known as ‘walk ashore’ pontoons.
Vessels on pontoon berths must be secured in the following manner
The vessel should be secured using adequate ropes as follows - two warps each bow and stern and two springs, one from bow and one from stern quarter.
Warps Additional warps must be left accessibly on board for use in emergencies.
Covers All covers are to be close fitting. Large spray hoods or similar open covers cause windage and place added strain on the warps and must be stowed when the vessel is on the mooring.
Propellers All propellers on exposed outboards must be covered by a bucket or basket.
