I'd bet if you really hunted around, you could still find a W32 hull floating around that has not been finished. Or the Atkin designed Ingrid 38 that was built in Woodinville.
Otherwise, I would wonder up to PT and check out the cape george boats.
I would also add about double the hrs as mentioned for any finish work, as many times you have to make up the jigs, where as a pro has the all finished, and some of those types of hrs are not included in the time to finish.
It took my step dad some 30 yrs to finish a Bill Garden design Sea Bird Yawl variation. He was not working consistently, These types of projects sometimes take longer than one thinks they will.
Yes T-bird plans are still available from the main T-Bird assoc, and Clark Craft in NY has plans, about $200 or there abouts IIRC. I can think of 6-9 places off the top of my head one can get boat plans to build in all types of materials.
She drives me boat,
I drives me dinghy!
