Really? You ever try to pay, feed and house 100 guys for a couple months? Then there's the heavy equipment and storage space needed for the wings.

I'll defer to Gino Morelli's earlier statement, that the easiest way to get the costs to come down significantly would be to go with soft sails. Only question I have is, how much slower would the boats be, and is that even an issue, if they can get them over 40 knots with soft sails, and they are all going about the same speed, does it matter if they are all going 45 instead of 40? It's a relative thing.
