I believe the pre 1980 boats had one board, the 1980 or maybe it was the 1981 had two, was MUCH lighter, and sold with Spinnaker, motor, trailer and Main, Jib, Genoa, cushions, and spinnaker gear for $27,000.00 give or take a few thousand. We had to have close to 20 knots of wind to get a hull up on the older boat, and it was a dog, relatively speaking. The newer lighter one would get a hull up in about 12-14 knots and felt much better balanced.
