Some one on another forum was talking about old US steamhips from the 1800's Some of you may not know that almost the oldest steam powered vessel ever built was a powercat. It was launched in 1788 in Scotland See here http://en.wikipedia.org/wiki/Patrick_Miller_of_Dalswinton and here http://www.gutenberg.org/files/31179/31179-h/31179-h.htm So if anyone says to you "your powercat is a dangerous modern invention" you now know what to say..... -- Best wishes Richard Woods of Woods Designs sailing catamaran designers www.sailingcatamarans.com
