They are all wrong :) Build Nick's Petrel at 95% sized forms, keeping the length 17". I really like it (I weigh about 135) and my husband is thinking about building another, as he likes it a lot as well (he's about 165). Great day boat and really good in surf. We have only had it out in small 3 ' or less, but it handles really well. If you look on the Connyak site, you can find pics of Nick in the original in big stuff.
