I have the boat up in the air in a sling. Some fiberglass and jell coating was applied to seal the centerboard I was told there is some play in the centerboard. How much play is acceptable? I am considering painting it with some antifouling even though I pull it out of the water after a day trip. I could opt to leave it in the water maybe a week at a time for trips to local islands, Isla Cobia for one.
