I finally took the plunge and made cutouts for three hatches in the V-berth today. I had everything plasticked off already from doing other foredeck/v-berth projects, and access to power and a good vacuum - so it seemed like the time. I was so curious what I would find in "the foam lottery." Would the space be empty, like the 2002 22 Carpy? Would I have hours of painful digging-out of expanding foam that would be also be stuck all over the hull like some others have? :?:
Turns out it was neither: The entire area under the v-berth is tightly packed with HUGE blocks of white styrofoam. They are not attached to the boat in anyway, but they literally fill up the entire space to the brim -- even being contoured for the hull sides. In this case I think they actually would have added good flotation. The foam cut easily with either a hacksaw blade or a sheetrock saw, but neither was anywhere near long enough, so I was unable to get any of it out today. Rats, I wanted to see that empty space! I don't have a long hand saw, but maybe I can find something like a long steel bar to slice it with. Once I can get a piece out, I'll be able to cut the rest into smaller blocks.
Ironically, when I was out at sea on a cruising boat, and could have used good flotation foam (in case of hull breach, etc.), there was no way to have enough and still carry stores, water, and gear. Now that I have an "inshore" boat, I'm removing it! The space will be nice, and also I like to be able to get to the hull everywhere, so I'll accept the loss of the foam. I briefly considered just hollowing out storage "wells" and glassing over the rest, but then discarded that idea because I'd rather be able to get to everything to clean it, see it, etc.
Anyway, long afternoon hunched over in the v-berth listening to the vacuum, jigsaw, Dremel, and Multimaster (even though ear plugs and muffs), but I'm very happy to have the hatches cut out. I also cut back the core in the berth flats around the openings - I'll fill that back in with thickened epoxy tomorrow. I think I'm going to use the cutouts for the hatch lids (no good plywood on hand or I might use that instead), but I haven't decided yet. I'll be adhering cleats below the openings for the lids to sit on, "sailboat style."
I'd post photos, but I left my camera in the v-berth, and I'm too tired to go back and get it :?
