Ada seems to be a scale up of cartoon #10, with a 'sitting head room'
cabin added instead of the crawling height cuddy.

After long thinking differently, I suddenly realize the Planing Motorsailer in your nice model isnot Ada.
The dimensions noted for a 30% stretch of Diablo in the cartoon come to 19.5 x 5. The note in BWAOM on Ada, pp. 324, says 26 x 6.
Ada is similar to a very stretched Diablo Grande, itself 18' x 6' 3" . It's more probably adapted from the 26' Texas Dory Sampan, much slimmed down. Couldn't find a drawing of that one handy, tho the Sampan Express 22 here has a cabin like the Ada photo seen in BWAOM.

Some random thoughts. 1) It was interesting to work out the air flow
around the sprit sail with jib, as I had no familiarity with this sail
rig, and it is wildly different than a sloop or gaff sail. 2) This is
a 'small' boat, with the cuddy being tiny. 3) The 'racks' for the
spars serve a double duty as "backrests" for the boat while motoring,
this is classic PCB genius via simplicity. 4) Overall, I am reminded
of Dovekie, or similar as this boat is designed to be an ultralight
trailer boat.
