I've read...
Hey Jerry,I read somewhere, when Catalina builds sailboats, the decks our put on before things are put inside the cabin. So it should be able to be disconnected and removed. My heater is under the quarterberth and it looks like it could be disconnected from power, hoses and lifted out. I don't know how heavy it. Let us know how it goes ? What type of heater are you putting back in ?CM
