I built a 28' from a kit in 2001/02, after 4-years in 2006, I sold it with 500 hrs on a 250 Yanmar, for 50k. I had the T-Jason 35' coming, it was then end of the season, and I was able to sell it without a broker. I even made a few bucks for that selling price. Glad to see them holding their value. I'm waiting to see my old 28' for sale again here someday.
I really can't answer that because we are talking 10-yrs from when I ordered. There is a new build going on that is going to be a center console I'd ask there or simply call Terry. 207-546-3323 or 546-2066. One of those number are disconnected not sure which one though. FWIW-I'm thinking my kit with engine was around 40k.
