Went down and checked it out. 4ft white caps inside the marina!! Almost had to crawl on the docks to get to the boat. NASTY stuff!! Damn North Winds. They are the kiss of death. Anyway I looked at the scuff mark, only on the surface. Definately compoundable. WHEW!!!!! Replaced the docklines and added a few extra bumbers. The dockmaster contributed the failure to tying to the dock to closely. Not enough slack in the lines to compensate for the fluctuation of the waves. A lesson learned, luckily not a t a great expense.
