Neil here in Northfield Mn. Thought I might ask for some advice before I attack my boat M15 #374 which I bought in SD last year. The boat had not been in the water for several years; after reading about problems thru the list server and inspecting the shoal keel/centerboard I filled in gaps in the centerboard trunk,repaired the aft edge of the centerboard which had a chunk out of it,and reinforced the leading edge of the centerboard all with west sys epoxy and thru it the water so I could get some sailing in. When I trailered the boat back home I found that the bouncing on the front trailer roller had knocked a chunk out of the leading edge of the centerboard. I've inspected the area and sanded as much off the top of the centerboard back by the rope hole that I thought I could reasonably remove.There still is about 3/8" to 1/2" that hangs below the centerboard trunk when the centerboard is pulled up especially toward the aft end. I am concerned that I don't repeat last year's occurrence.I was going to epoxy some wood to the centerboard trunk in the area that the trailer roller contacts the trunk at. I also epoxied the centerboard pivot pin in last year.What do you all think? Neil Hull #274 M15
