I've posted about this dockline arrangement before but, after spending
the night on my boat in 25 gusting to 40 at our outermost slip with a
several mile fetch to windward, I've got to say it is worth repeating.
I could hear other boats snubbing and banging and saw several frayed
lines in the morning but I slept soundly without ever feeling a jerk
or a snub.

The arrangement doesn't interfere with the a boat on the opposite side
of the slip and one could use the same arrangement attaching to the
cleat on my side.
