Insulating the boat for cold

Post by Pembquist »

The boat gets a fair bit of condensation sitting in the water in winter. The little cubby holes at the salon births are pretty bad. I read about someone adding that bubble wrap stuff under the ash strips in the V birth. I am curious if anyone has done a thorough job of insulating a Cape Dory. I watched a video with Roger Taylor talking about his Ming Ming and he used glued on indoor outdoor carpet squares which sounded like a potential petri dish to me but what do I know. I was thinking of 1/2 or 3/4 extruded polystyrene glued to the hull at least above the waterline. My fear would be the flammability of it all and also if it would eventually just soak up watervapor and grow mold. Any body worked on this problem?

Also It feels like the void between the hull and the liner at places like the hanging locker could be filled with pour in or expanding foam, I am assuming there is a marine version of this, any downside to this?
