Large Vessels Berthing at Floating Moorings
Waterways Ireland wishes to advise all masters and owners of vessels with an overall length in excess of 11m, particularly those constructed in steel, of the following points in relation to berthing at floating moorings and also on finger jetties having a length of 9m:
- These vessels cannot be secured properly over their entire length thereby placing extra strain on the pontoon mooring cleats as mooring lines are doubled up.
- The large overhang of these vessels creates an obstruction to other vessels trying to manoeuvre onto the berth especially for novice recreational boaters and hire boat crews with limited experience.
- In adverse weather conditions of high winds and /or flood conditions with high flow rates there is a greater risk of breaking free of the mooring and causing damage to other vessels and the mooring infrastructure especially as these large vessels are primarily constructed in steel and are very heavy.
- The 9m finger mooring is designed for vessels with a max overall length of circa 10-11m.
- The fixings attaching the floating mooring to the main spine can be compromised due to excessive forces induced by inappropriate sized craft leading to premature wear.
- Such vessels place excessive strain on the mooring piles and anchor chains as water levels rise especially where masters have secured to both the cleats and the mooring piles themselves.
Masters of such vessels are requested to berth on appropriate lengths of fixed quay wall only. Waterways Ireland thanks its customers for their cooperation in this matter.
