quiet night, woken up 2am-ish by something, up on
deck, to find I'm drifting slowly towards the next
boat in the mooring field...I probably shouldnt have tied up to a mooring ball with a pretty good beard hanging off it, but no harm done in a dead calm.
On my own swing mooring I do regular inspections and replace the
rope at no more than 2 year intervals - ( actually I dont replace it, I add a new
rope and keep the old one, marking it for
removal at the next cycle).
A well laid, properly maintained swing mooring is more than adequate to hold the vessel its designed for in any conditions in its area.
