My son is going to use my old -- 1974 -- Worlds boat, for his sailing lessons and first year of beginner racing. This boat is a good ol' boat -- seen lots of use. Now it leaks a bit, and we need to fix before the season starts 6/30. (It's been in the garage all winter, and so is good and dry, inside and out.) We have to repair: 1) drill holes from where the compass and old clam cleats, etc. were mounted; 2) I'm sure the splash rail leaks, and 3) old hull repairs, especially around the bow. The old repairs were done with epoxy and micro-balloons, and it looks like the repairs have deteriorated, the same way an old filling for your teeth would. Any thoughts on what fill to use, that is easy to apply & sand? Can I use silicon sealer on the old screw holes and around the splash rail? Any tricks of the trade to get this hull dry and back in action? I would dearly love to see him use this boat, but I worry that I won't be able to get the hull integrity back, the foam will get wet, and he'll be slow and sad!Thanks much, BMF
