mooring buoys

[Graham376]

We were going to change to polysteel but a 40 ft Jeneau had to go on a temporary one we laid & within a week it had swung round in the wind ( partly aided one expects, due to not having the weight of chain) & the back of the keel cut the 38mm polysteel like a knife. the only boat we have on it now is a drascombe. I would advise against polysteel in tidal waters.

Virtually all the failures we have seen have been chain, swivel or shackle pin failures, not risers. Only polysteel riser failure I have seen in 13 years there, was where a thimble had rusted away and the shackle chafed through the loop. We're in sheltered tidal waters but a big spring range is only around 3m.
