Gato: The link you posted is the definitive Blade building gallery.
About who the plans are for, you have a point there. We all want different things from building plans, just as we have different skills and experiences. I suppose Phill can say more about this, (why and who) when he is back. I am sure you will have no trouble getting foil crossections and geometry specifications from Phill.

Yes, there is a Yahoo forum for Blade builders on: http://groups.yahoo.com/group/BladeCatamaran/

It has been inactive for a while now. I guess Phill is handling most of the questions directly by e-mail and dont have time/energy for the forum.
