DillyDilly was a fresh water boat when I bought it. Swantown Marina in Olympia is at the southern end of Puget Sound where heavy fouling is a problem and effective bottom paint is required. I plan to keep the boat is the water ~7 months/year.

Using 5 coats of Interlux 2000e and 2+ coats of Interlux Micron Extra, I followed the instructions carefully. Everything went well until I reinstalled the centerboard and discovered the combined thickness of epoxy and paint on all the surfaces caused the board to bind inside the trunk.

I scraped all the coating from inside the trunk and the thickest part of the board and recoated with bottom paint only resolving the bind problem. My understanding was that a 1992 model does not use steel punchings so swelling due to rust was not a concern.

I also replaced the centerboard pendant. It was possible to expose the knot with the centerboard in place but not jammed against the front of the trunk. I took advantage of that fact when the board was installed the second time.
