Re: Hull Material ??

["Marsee Skidmore" <heyred@email.msn.com>]

I am also under the impression that ferrocement has a poor reputation in
yachting circles, and not all of it deserved. I'm not aware of any inherent
weaknesses as a hull material, but there is a wide variety in quality of
workmanship. It's hard enough to fair the hull on a blowboat, when you've
got ready access to both sides. How would you manage the same with a psub,
when access to the inside is restricted? :-o Joe
