I was wondering the pros/cons of the location of foam in a small 12ft fiberglass boat. The two boats I am considering have foam in different locations, both of which meet USCG "unsinkable" flotation. Carolina Skiff J12 has foam under the deck only, nothing on the sides/gunwale area. Caprice skiff (which I owned in the past) has a 12ft model that only has complete side flotation. My question is why is one done over the other? I heard the Carolina Skiff can topple over while swamped, and side flotation helps keep the boat upright while swamped (Whaler?). Any info would help, I am considering getting the Caprice Skiff 12ft again and maybe adding 1in. of foam to the floor itself in a few spots.
