Yea Six in one, Half Dozen in the other..........
The Salon was gonna end 3 windows back- roof raise through the galley,bath,and bunkroom -leaving 2 low windows in the M.B.
Was gonna cut an inch and a half out of the tin and build P.T. bulkheads out of laminated 3/4"ply
leave the ribs low too keep the original framing for the windows then run the "new ribs" high .
The back roof raise detail can be buried with a V/W style metal & wood roof rack
The front aerodynamicness????????????????????????? I should start a thread elsewhere for that, I would like to come up with some watertight sheetmetal detail, but it will probably end up being fiberglass
I could really use 2 extra ribs too make my framing sturdier.
