Hi Ed, I as well as others have had similar problems with forms 9 and 10. I assume you are refering to the corrections posted for the book on nick's web page as well as the rest of the info from the book. Back in july I asked questions and decided to replot these forms. This is what I got.

I re-plotted the data points for the problem area as follows: Station 9 Buttocks Deck 9" - 4.80", 8" - 5.75". Station 10 Buttocks Deck 9" - 4.80", 8" - 4.84". Water Lines Station 9, 6" - 7.68", 5" - 8.81". Cock Recess, Offset Station 9 - 8.59" Station 10 - 8.76". This info should correspond to the table just plug in the new figures. This is what I used and it worked fine. Just so you know the results I originally got ended up with a notched area where the section that gets cut off for the cokpit is. Nick indicated that the form should be fair all the way around and the numbers above give you that. Hope this helps. If you have any other questions look back in the archives in the begining of July this year. Thats when I had problems.
