I've been plotting the cross sections using Nick's book and the Guillemot table. Have there been some errata issued for the numbers? I'm having difficulty with stations 16 and 16 1/2. Both have keel locations that are higher than some water line offsets listed below. I don't understand that. For example, on station 16 the keel (presumably the lowest point of the cross section) is at 1.56, but there is an off set of .08 for the 1" water line. If the keel is above the 1" water line, how can there be an offset for it? If I'm totally missing and this is a stupid question, chalk it up to my absloute lack of experience and accept my apologies in advance.
