I think of ferro-cement in the same way as I think of Bruce Roberts designs: 9 out of 10 of them would make excellent bathtubs or planters. But that is not the fault of the designers or the materials, but the amateur skill sets of the builders. For all I know, the knock against ferro's reputation lies solely in the inability of home builders to execute properly. I've seen some appalling home-builts in fibreglass, as well, but at least they can be insured.

I have seen some excellently finished and reasonably fast ferro cruisers, just as I've seen fast boats in steel. Just because it was popular with the DIY crowd doesn't mean it's an intrinsically inappropriate hull material.
