Does the '68 have the original long boom? The newer boat looks to be in much better condition...except the engine.
I happen to know of a '73 that is going on the market in a matter of days. It is farther away from you, but a freshwater only boat with Westerbeke engine with approx. 1800 hrs., New sails 2011, yawl rigged (one of only 25 built) with new roller furling, updated interior, etc...
