Thanks Bruce, no need to apologize. I am extremely grateful for this amazing resource. I can well appreciate how errors like that can slip by one’s attention. I’m relatively new to these design figures and that’s why I didn’t spot the error initially.
In my search for a boat your site has made it such a pleasure to compare the different boats, it’s almost becoming a hobby
Incidentally, the NC43, the big sister of the 40 also seems to be calculated the same way, no doubt from the figures given.
I couldn’t get the figures for the straight 44 but these are for the 441 which may be the same.
