I only know what I've read regarding sailing canoes. Ideally something with more rocker than the Blazer would be good, but the Sebago club (ACA) in NY made good use of Blazers and Rangers for sailing. I've corresponded with a couple individuals that used the Blazer/Ranger too. Compromise to be sure, but they have worked well enough.
I'd be interested to know about your stiffening tricks! Always willing to learn...
