It is horses for courses. The minhunter, even though she was the size of a corvette, was built in GRP to be non-magnetic. Of course, aluminium would have worked as well but at what cost?
Jeanne is of course right. It is the cost of building which, oncce basic parameters of strength etc have been met, that dictate the material to be used. I suppose, if cost was no object we would all be sailing boats made of titanium.
