Interesting variation on the theme. I'll leave Rob to comment from a design point of view. Let me comment from a fellow cruiser in spe point of view.
Clever are: 1/ using the wind shield window sections on the ends for bringing light in bunk and saloon - no need of additional hatch? 2/ The simple three piece cabin top is tempting.
Concerns are: 1/ the roof mounted windows will be very hot in the tropics (shield with roll-on roll-off sheet of solar cells? 2/ is the lw hull high enough to steady for a stayless mast ? 3/ proportionally to the length the ww hull windage may be concern 4/ the windows on ww side are grand but vulnerable to ww wave action
