What an idea. Maybe sell the concept to Hobie, since they are obsessed with making strong, heavy, durable boats (No, I`m not criticising Hobie, they make great boats, just too heavy for my liking !)
I think ferro-cement boats only become feasible once you exceed 36-38 ft length in keelboats, not sure about cats. I`ts all about the volume of air contained by the hull vs. it`s mass. You also have finite limits for the min. skin thickness to deal with which means that the hulls would weigh more than the volume could support.
Make mine with a periscope !
