I will post photos as soon as I am done. It was an interesting problem and if seeing it will help somebody else correct a potential life endangering problem like this I will be most happy. What I hoped I would do by adding this post was alert folks who assume their little boat has flotation, that it may not! One of the very attractive things about a catboat is its safety. With a barn door rudder that doesn't extend below the skeg and its beam to length ratio, the boat will usually round up before it capsizes. This is an important feature in these cool waters off the coast of Maine. To discover that my boat would have probably gone to the bottom if it had capsized was disturbing. I was expecting that part of the design and construction was sound since there was no way of inspecting it without considerable demolition.
I poured this foam. That process has pitfalls and I will be glad to discuss what I learned if someone wants to send me a message.
I have also sprayed foam. For the catboat application, I was just filling the spaces that are the seats, a pour was adequate and much less expensive than a spray kit. A quality spray kit will allow you to fill almost any void completely and quickly with minimal mess. I filled the space under the cockpit floor in a Rhodes 22 with a spray kit. All that required were two, 2" holes. With the rest of that kit I filled the voids between the deck and the liner and it resulted in a very positive flotation calculation for that boat.
