well, we've kinda chatted about this a time or two. you should know how i feel about the boat i have; it ain't goin nowhere ...
but, i didn't chopper it although i've only owned it since '96. i know the names of the previous owners, but have never been able to find them. but the point really was, this is a very heavy boat, considering what it competes against, either river wise or track wise. materials available today, in addition to c/v and kevlar, can be used to build an exceptionally strong boat without the weight. the question is more along the lines of how much weight is enough.
btw, i have no use for a placecraft. for me, it's swtd. give up your fuel talk; put a pc next to me, same hull weight and same hp, and let's see what happens.
