You are new here, as we all were at one point, so I'll explain. What Dave means is on this site we all use our real names. It makes it more personal and we all seem to like it. You'll also find on this site there is hardly any "keyboard heros" or arguements because of it. No one hides behind an anonomous name and hurls insults. We know there are other sites that use "handles" or whatever. On every other site in the world I'm cwa1104sab, but I'm Sab on here. I have spoken with guys on this site on the phone for hours when I was looking into plans for my boat that I'm building. It's just the way it is and we all seem to like it. So please, introduce yourself, and we'll all be happy to help you.
As far as your question, I thought about those plans but I decided they didnt fit my needs, big water but also very "cancelable" in Andrew's terms. They do not seem too difficult to build though.
