Why not just sand the ablative very nicely with long boards and fine paper - down to 400 wet. That will give you a very smooth bottom for next season. Next spring, launch it and let the paint continue to ablate, like it is designed to. The more it ablates, the less work you will have to do to prep for VC17.
I will certainly take that into consideration based on what she looks like at haul out, but that would be the easy way out. Iím just not happy unless it takes 3 times longer, is twice as difficult, and the aggravation level is 10 times higher to achieve the same result.
Honestly though, because we are racing the boat, Iíd like to get the bottom as drag free as possible. We found several large areas where the paint had flaked off when we hauled out last year and itís probably time to strip it down and start over. I'd really like to see what is going on beneath that old paint anyway, just to make sure everything is OK.
