<<Is anyone else concerned about how the engine on the dinghy will handle in reverse (like when docking)>>

  Yes and no.  This is essentially what the Wharram catamarans have been doing for decades, and I've never read about a serious issue with it.

  You could probably hook up a system to prevent the dinghy's stern from lifting if you give it full throttle in reverse, but first I'd see what actually happens.  That's a long dinghy with a significant amount of weight on the transom and a gradual slope up to the bow.  It would take a lot of thrust to lift that out of the water if the trim is neutral.

  My bigger concern would be having the motor swamped by an unexpected rogue (semi-rogue?) wave from the stern.

  That said, there are outboards out there designed to handle being immersed for short periods.  I think Yamaha makes a multi-fuel jet outboard that can do that.  Well, they call it multi-fuel, but it really wants clean gas.  It will burn diesel and jet fuel, but more as a "get me home" option.  The motor would need some cleaning and service after that.

I think the new cruiser is really pretty, but I am having difficulties with seeing it as a long term cruiser, or live aboard, because of a lack of storage. When I look at the galley area, I am assuming that one of the cabinets next to the stove is a refrigerator, so there is only a single cabinet in the galley area to store all the cookware, dinnerware, utensils, appliances and food.
 
My initial approach to this would also make it more of a tropical weather boat. I would remove the wall between the saloon and the cockpit, allowing entry to the seating from the cockpit side. Then I would take 12-18" out of the table and put a set of cabinets there, so that the galley has twice the counter space and 4-5 times the cabinet storage.
 
I would also make the slanted windows hinge up, allowing a fore and aft breeze. That should make up for the glass generating heat in the sun, by allowing them to be open in the sun. When the weather is bad, just hinge them back down. Add mosiquto netting when they are up so that it can be open without the bugs.
 
Is there any way to get the sheets lead back into the saloon? I don't like the idea of having to put on all my foul weather gear every time I shunt? If that isn't practical, I would add a bimini over the deck (is that what it is called?) area. It is nice to be able to steer from the inside, but there has to be at least basic sail handling, or it loses much of its advantage.
 
Finally, I would take out one of the heads, to put in more storage amidships. I would put the batteries and water tanks there, low down in the middle? I guess I should ask, where are the batteries and water tanks in the current design?
 
If possible, I would prefer to have a small head in the lw hull, shared between the two bunks. Just so that people don't have to cross the dinghy in the middle of the night. If not possible, I could live without that.
 
Is anyone else concerned about how the engine on the dinghy will handle in reverse (like when docking)? How do the throttles, etc, get run to the wheel, so I can steer and motor in close quarters?

It'd be easy enough to make the windows vertical with overhangs.  probably easier than without, in fact, but I agree, it would not look very nice.  Also agree about tints.  Looking at blue sky through grey tints is not pleasant.    External louvres are a solution, as is double glazing (heavy, but so are louvres) and reflective glass.  My preference in the tropics would be for plenty of ventilation, as much as possible cool air under the bridge deck exiting through ceiling hatches. 

Making 2 heads into one is easy enough, and the extra room would be handy. 



how long is the windward hull Rob ? 

10m/33'

any idea of the bridgedeck clearance?

600mm/2' under the cabin, which overhangs the ww hull by 2.4m/8', 900mm/3' under the rest.
