Val's post remined me that, in any good discussion of the merits of Steel boats, one shouldn't forget Concrete... sorry, "Ferro-cement".
I'm sure there are a few of these creatures still left that, if made well, are the lightest and lowest-maintenance "steel" hull form you can get, but if you hit something, like a reef, it's a swim for sure(shore).
BTW, Val.. How ever did they rescue your boat? Lot's of cranes and a new cradle perhaps? ...and why were they moving it with the mast up??
