I think the boat could be righted the way Rob suggests, as long as there is enough flotation in the mast and boom, but I think that in order for there to be enough flotation, some kind of mast and boom float(s) will be required. The boom float will likely need 200lbs of buoyancy to work in any kind of swell, and I think it would be difficult to winch the lazy sheet from the skyward hull enough to right the boat in flat water - much less in 5' to 7' waves.

I know Rob is all about flat panel hulls these days, so instead of a leeward pod on the leeward hull like jezzaro, how about a cylinder like hull on the leeward side of the hull to help prevent capsize. It could be inflatable, so it shouldn't add too much weight. Seriously, if the goal is to provide a boat people can charter in a race they have never done before, sailing a type of boat they have never sailed before, I think training wheels aren't such a bad idea.

I've righted my 32'cat at least a half dozen times using the mast float, so I have an idea how much force it takes to right a bigger boat. I can tell you that without some kind of gin pole to change the angle of the lazy sheet there are going to be some significant issues with the righting procedure, and a nacelle or leeward pod will give you the needed reserve buoyancy to help prevent capsize, and provide the needed angle the lazy sheet would require to right the boat.


Rob,

Why not go all the way and make the boat a foiler??


Use the foil configuration found at the bow of C-fly on the leeward hull.
