I think your Cataproa design is very versitle. I especially like the light weight made possible by keeping the rig loads off the crossbeams, keeping the boat small, reducing surface area where possible and limiting the cabin width? to about 30% of the beam of the boat.
I think Cataproa's asymmetry opens up an entire range of possibilities normal catamarans or trimarans cannot use. For example, concentrating weights amidships will reduce pitching. I like that Cataproa has quite a large cockpit and at full capacity, the boat will not be out of trim. This is accomplished while still having a small but usable cabin.
I think the narrow hulls (for a cruising boat) and low lever arm on the rig will allow performance far better than other cruising multihulls of the same size. If not afraid of capsize, I wouldn't be surprised to see up to 19 knots in ideal conditions. With my old boat, a Windrider 16, I reefed when the boat speed hit 13-knots or when seas became big enough to start burying the amas. It would hit that speed in 17-18 knots of wind on a reach. I personally would probably not drive Cataproa that hard. I will propbably put the first reef in when whitecaps begin to appear, i.e. roughly 14-knot winds. I don't want my talking about reefing to obfuscate the advantage Cataproa has because the low rig center of effort allows more sail area and thus produces more speed compared to other cruising multihulls of the same size.
Actual construction of my Cataproa hulls will start late October or early November.

Hello David
Looks interesting. Nice that the design leaves so much freedom for additions. When will you start the build?? Please keep us informed.
