Re: Pearson 36
paul, I don't think Pearson ever was known as a light air boat, any of them. Well made, solidly made, but not so much "light air". On the Hudson, between ducking traffic, and the tidal flows, and all the twisty parts, I'm not sure that would matter since you may wind up lighting the engine more often than not.
I haven't sailed north of the TZB, but I've seen the river and the river traffic many times in many places. A real light air boat...something like a retired J/boat would fill that role better.
And for a liveaboard, the P36 might be too much cockpit, too little cabin for you. Or coming up from a smaller boat, that might not matter. Nice that they put the wheel up by the traveler to make shorthanding easier though.
