I looked at the design and they indicate the boat was built at a "reasonable cost" and I don't see the cost. IMHO if the cost was truely reasonable they would have included the cost. http://www.lymanmorse.com/boatDetails.php?boatID=81
It's a good size boat and I don't see that it is anything really exceptional. The most exceptional thing would be that he is single handing the boat and that is something I hope never to do. Sailing double handed is well enough work!
