May be a stupid question but I can't seem to find the answer anywhere. I just bought a 94 Four Winns 215 Sundowner Cuddy Cabin and would like to know if it has flotation. It has a large area on either side of the of the boat, under the deck, that appears to be completely sealed. I would imagine that these areas are filled with foam but would like to know for sure. |

I cant say for but my 88 Horizon 200 definitely has it under the deck. In fact I had to dig much of it out when I fixed the rotted deck and stringers. When I contacted 4winns they said that it was needed for both flotation and structural reinforcement. So I wound up replacing the foam when I did the new deck back in 07. |

All USA powerboats in this category have had flotation since [I think] the early 1970's. Here is a link to a US Coast Guard regulation requiring "Level Flotation" in the case of a swamped boat: http://www.uscgboating.org/regulations/boatbuilder_s_handbook/flotation_part1_f.aspx I know that the typical sailboat does not require flotation. They will sink like a rock if the cabin fills with water. I do not know at what size a boat, yacht or ship no longer requires level flotation when swamped. Perhaps someone else has that answer? |

Over 20' does not require it. But many do such as Boston Whalers, Key Wests, Grady White, and Everglades. |

LouC, you are correct. The regulation only covers powerboats 20' or less. Outboard boats must have "level" flotation, and Inboards and I/Os must have "basic" flotation, which is similar, but can be stern low. This is with engine and gear, and a portion of the people weight. I had thought that my Horizon 240 would float if swamped...but it might not. The regulation does not require it. |
