I know you're good, John, but how can you tell the year of the boat at 50-mph? Ha, sorry about that.
Could it be the only one of the 15 made in 1968, with a bunch more of em left over here and there around the Great Lakes from larger production runs? I think it would be a desirable boat, by the way, we sure loved our 1968 35' Sea Skiff Clipper.
