Richard, are there factors other than the Zest heritage that made you stick with a more dinghy-like main hull? Ditto for the Tryst/Duo design.
What I really want to know is what difference in performance one can expect from a much more slender waterline beam.
The Italian 10ft Diecipiedi development class trimarans seem to lean towards super-skinny hulls. Would the much greater displacement/length ratio of a 10 footer call for a different set of design decisions if speed was the goal?
