Gord, you come up with some of the most interesting links. Mahalo for your search acumen.
Had completely forgotten about the Westsail construction manual. It was a nice to have guide for building our boat. We got the 'precut' plyywood kit but for anyone who didn't, the cut layouts for the sheets
was a treamendous time/material saver. I say, nice to have, because it is how the factory may have done it. If you had a question you could reference it. It was not necessarily the best way to do something, however, and wasn't necessarily done that way by the factory as we found from reality.
We built our boat a few blocks from the original Westsail factory. Had a good relationship with Westsail and some of the workers. Was able to go over and check things out a not to interfere basis, usually after the workers had gone. Found that that was a much better way to figure out something than the manual. Unfortunately, that option isn't there anymore and wasn't for most people building their Westsail.
