there's quite a few for sale. Almost all are over seas, look in nice shape, and sell for under 200k. 65' plain jane.
Sort of a clever idea in it's day. I saw one once sailing on Lake Champlain in Vermont. The boat was out of scale with the whole setting of lake and mountains, way too long, way too high.
I know the M65 was moving fast - it was stiff as a stake and very close to the wind- but as it tacked, the whole scale of the boat made it look like the scene was in slow motion. I hadn't smoked a joint, either.
