It seems to me that you are not a fan of steel hulls. Will I trouble you if I ask you why?
Grafare, Welcome to Sailnet!
The 'steel or not' debate is a well documented one with obvious and passionate views on either side.
I'm sure Paulo will come back, but he may be asleep by now... In my view a steel boat is really only specified if one intends to do polar sailing or extreme venues like that (or you plan to play 'demolition boat' with every coral reef you come across!
Modern techniques and generally far better designs can be rendered in typically fiberglass, or possibly even better, cold molded wood/epoxy. Go back through Paulo (PCP's) "Interesting Sailboats" thread for some ideas on what's happening mostly in Europe of late.
The 'economy' of steel is often overrated as what ever hull material you choose will end up being a low 10-15% of the overall finished cost of the boat fully finished and equipped. In that respect the 'cost' of the build (of the hull) is not a major consideration overall.
There's no denying the inherent strength of steel, but if it really was the best choice one must ask why, as Stumble pointed out, there are SOOO few steel boat builders left. A well engineered hull of any other material can be nearly or perhaps equally strong, (and certainly more than 'strong enough' for typical cruising and safe boat handling) and ultimately will be lighter, faster, and probably better shaped.
Had I the ability to specify a new custom build, my first choice would be a cold molded hull, with perhaps a molded f/g deck, though the tooling costs there might be excessive... and, most probably, from the drawing board of Bob Perry...
