wingsail is not a true rigid wing sail and is reefable, supposedly fairly easily.
I'm also trying keep the masts pretty short and keep weight to a minimum. More sail means more beefy structure and more weight, more weight means more materials and more rigid materials. All this equates to increased cost and complexity and reduced ease of use and safety
I want safe, simple, frugal, even if it means I get around a little slower. But I really don't feel like if I stay in the tradewind belts that 200 miles a day is a stretch. But, alas, I have little first hand experience, so here I am to make sure I'm not getting ahead myself.
It seems to me you want your hulls to be like a giant beach cat, but with an Optimist sail...? You say there will be no accomodation in the hulls, but if you build a pod or cabin
between the hulls, this will add to your windage, strength and construction issues. Wharrams, Woods, and Harry Proa all use the hulls for accomodation (as do all other production cats, albeit with huge central cabins as well).
If you are serious about your design, build a 20' version first to test in the real world. Otherwise build or buy a small Wharram
and get experience with that. There are a number of Tiki 38s cruising the world, some posting
on Youtube. They seem to get very good daily runs in the right conditions, and are safe, easily handled boats. Why not build one of those and add modifications to make it your boat?
