Dennis,
That is extremely cool. Thanks for pointing out the video link. You
could probably do this with a purpose-built trailer and a stub mast in
a separate socket (1/3 full mast height, used to lift the primary mast
at its center of gravity) , no crane required.
Now I *really* want to see you build it. I've said many times that i
want the largest trailerable boat I can get, and this would certainly
qualify. Actually, I'd be willing to put up with a 12' width, but
fitting into 8.5' is even more impressive.
I had actually brought up atlantic vs. harryrproa in a post right
before the one you responded to, but for some reason the post didn't
make it. (thus my comment about ignoring my question about how the
boat goes on the trailer).
I'm partial to the harryproa design for the following reasons: a)
more space in the windward hull, b) heeling moment decreases, or
remains the same, as you fly a hull, while heeling moment increases
with the atlantic design, c) stresses are in line with the hull, while
the atlantic has to translate rig stress through the beams to that long
leeward hull, and d) the possibility of popping back up after a
knockdown.
As far as handling the sails, a leeward design might offer more
safety in a schooner configuration (from the tramp), while a single
mast would probably offer safer sail handling with the atlantic (from
the cockpit).
But I'm sure you're familiar with all that. Your design has more
than enough space to deal with masts in the windward hull, and the
taller leeward hull needed for a rig there might get in the way of your
trailering setup. As long as you don't sail on the very edge, there
shouldn't be any issues.
I wouldn't put on a pod for safety as cavalier suggests. If you're
sailing an atlantic proa hard enough to fly a hull, in anything other
than flat water, there's a good chance you'll be going fast enough to
trip over any pod small enough to justify its own weight penalty.
What are you planning for steering and leeway resistance?

Hey Mike,Did you see the video... on post #9. It might clear things up. Unless you've already seen it... :)Also, I'm still bouncing between Atlantic and HarryProa placement of the sails (windward, leeward hulls). I've got pros and cons on both sides and the tally list is still balanced. Fortunately, the hulls and internal configurations don't have to be changed either way. So... I've got PLENTY of time to decide.Dennis
