Y'know George, I usually skip reading your posts because they tend to be so anal. This is another good example. The content of Nick's book surpasses that of the other three main stripping books (Gilpatrick, Hazen, Moore). I suppose you've insulted those authors too?

I would much rather paddle one of Nick's works of art than paddle one of your boats, even though yours might survive being tossed off the roof of a highrise. In fact, it's a wonder you even have the courage to pick-up a tool to start building a boat knowing just how many material failures are possible.
