I understand the reason for the puzzled statement (as do those in the know), it always appeared to be a double exercise, but in retrospect, for a one off it seems strange, i.e. the love and attention some go to build the plug seems a waste and why not build the boat from that, but if its for a GRP, that's going to have a lot of strenuous work done to it then its worth while, but how many 'plugs' are out there that could find a commercial market, negative plug for the x boxes etc could still be used for other modellers if the owner is so inclined to pass it on.
