Our docks don't have any
cleats, we have large pillings.
Round Turns and hitches for us.
When I form the round turns, I always make one or two turns, than on the next one or two turns I place the bitter end under the previous turn and than tie my hitches.
I'm not sure where I picked that up but it was many years ago from someone on the docks.
What is that knot called?
Its really just a variation of Round Turns but I don't know the exact name.
