Yes we did, but that seems like a long time ago now, and I wanted to take the opportunity to reiterate. The latest designs seem, to me, more like scaled down A's and, at least by appearance, seem to have lost any bouyancy (compared to early conceptual drawings) but obviously I'm no designer.

I won the set of DS-12 plans (thanks again!) but have been reluctant to proceed with a build as yet due to my "perception" of a limited upper range of weight carrying capacity. Is was awaiting more reviews, so Wouter thanks for asking the question.
