In our Hurricane Hole location we still try to relieve the dock loads in season.
This is done by using "pins" ,,6 or 7 ft long 8 inch piling cut offs located on shore about 20-30 ft from the water edge.
These are dug in till only about a foot is visible.
By securing to the pins fore and aft , and crossing extra lines much of the gust loading can be absorbed.
Old anchor line is used as many line lengths are boat long , plus the land poerton.
About 4 100ft lines are the norm , heavy being better for less initial stretch.
