Hi Paul

The #12 is what I intend on using on my Walrus ( 18' ). Too many negatives about the use of the 10 oz. and the #12 is a bit heavier so, figured that it would work O.K.. The newer urethanes would help in being a bit stronger, and possibly more puncture-resistant.

Any chance you could re-post your numbers for the shortened forms? Some folks might be scared off by the huge forms that Putz uses in the book. I'm using your version for my 18'er and I modified them a bit myself. Just cut out a lot of extra plywood to save material. I used the site which Mike Hanks brought up. Couldn't find it after that. Thanks for the time you put into re-working the forms.
