Hi, I’m not a papercrete expert by any means, but after having researched it for some of the purposes mentioned below It seems that the open cell nature of papercrete makes it vulnerable to saturation by leaks in whatever sealer one might use. There are ways of venting it to dry it out again, but it’s probably not the best choice for insulating a boat hull. Vermiculite and Pearlite have been used successfully with engineered mortars and reinforcement for lightweight structural cement boats. There is more about the later in Ferro Cement Net Archives.

I’m not saying it can’t be done, yet I know no successful examples.

I thought I was the only one with that thought. Of course,mine was
only for local lake use. I like the lightness of PC ,but I think I
would still have to use a wood frame and possibly a fiberglass layer
over the papercrete to make it work. My plan was to make it electric
powered in a catamaran style hull. I look forward to anyone posting
