My boat M17-496 (1992) has been in the yard for barrier coat and bottom paint. I'll be mooring it seasonally on Puget Sound. I applied 5 coats of Interlux 2000n followed by 2 coats of Micron CSC including the centerboard and inside the centerboard trunk. When the board was reinstalled, it jammed in the down position and was unable to be retracted more than an inch or so. I scraped all the paint and much of the barrier coat from the board and trunk to restore full motion of the board. There is still a slight bind about midway through the motion. It seems there is not enough clearance inside the trunk for the additional thickness of the coatings - probably ~0.050" . There was no visible defect to the board or the trunk before coating. Does anyone have input as to a solution? Should the centerboard trunk/board not get barrier/bottom paint? In order to paint, I'll need to remove some material to make clearance. Jeff Olympia WA
