CS 27

[fido]

I'm looking to up grade to a larger boat, c&c 26 wave or cs 27 3'11" draft, there is lots of info on the net on what to look for, the bottom of these boats, blistering seems to be an issue but if the bottom coat is apoxy this seems to fix the issue, why is this a problem in the first place, as well as moisture problems around the eletric conduit through the deck, and sea cocks, what other issues should I look for when looking at these boats
