Unlikely there will be structural problems if you get the engineering and details right.  The looks are a different issue.   The folding 40 and the cargo ferry both have cut away decks between the masts.  Looks weird, but can  be done.

Hello, all. I've been messing around with designing the layout of a HP I would build for myself if I pulled the trigger on a multi-hull that would be under 12 foot width. My layout's WW hull and cabin are under  12' with a bridgedeck wave clearance height of 3'. The cabin headroom on the bridgedeck is 5 foot. So that's what I'm going with. 


The intended sailing waters are the Intercoastal Waterway, Florida Peninsula, Eastern Seaboard and The Great Lakes. And I may even dare a trip to the Bahamas, too. Sailing would be from Oct thru May. I'm retired and have space on my property to store a 12' wide trailer and 40' length. 


So, my ongoing dilemma in my design spiral is how to approach the leeward hull design. My bridgedeck longitudinal length  is frozen at 18' to sit between the two bridgedeck beams. But in it's present form at 12' road width limit for a non-pilot car maximum, and I have another 3' or so of LW hull beam to "tuck under" the bridgedeck. I've been left with a big chunk of LW hull omitted between the beams to clear the cabin when the HP is compact for transport. 


That would mean a LW hull at slightly less than 3' from sole to topside spanning the area between beams. Then the LW hull topside abruptly rises to accept the beams. Not pretty. And the schooner masts position for a full hull depth bury is another story that I'll address when I fully flesh out how I would approach that sticky wicket.


Did I screw the pooch in compromising  the LW hull's capacity for reserve buoyancy and structural integrity? 


Any advice and opinions welcome,


Bob
