I posted that we finally found a boat. We're lucky that it was bought, new, by a member of my son's yacht club. Then two years ago one of the kids my son races with bought it. We bought it on Friday. We know the complete history of this 1988 Laser. It was sailed by the original owner about ten times a summer. It's never been outside in winter. Then the last two years it was sailed July and August. It's in great condition and all foils, rigging (6:1 outhaul), tiller and extension, XD cunnngham and sails were replaced new in 2014. So, in short, it's well maintained. The only problem ssems to be the result of an incident of gunwale versus dock. There are two sections where the gunwale is scuffed up. How do we fix this? I assume this has been asked before and someone will know of the thread. I am attaching a picture of the spots in question.
