Mike,

I'm really enjoying watching your progress - thanks for keeping us updated here!

With regards to powering up the design (and pardon me if you have already considered this), but beam is not going to be your 1st enemy when powering up this animal. Having worked with some RC multihulls and sailed my fair share of various tris and cats, the limits to the power really comes to play in the bows when maneuvering and not so much hull flying. I had a very lightweight one meter catamaran with tons of beam and it had so much righting moment that flying a hull was actually difficult...but it would pitchpole in a skinny second even sailing upwind. There is such a thing as too much righting leverage. I can't wait to see your progress every week!
