Greetings from a new member. I owned a 1976 Alcort for seven years and upgraded to a larger daysailer, looking to go back to a Sunfish. I'm talking with a seller in a neighboring state, the boat has no hull number, so it's definitely pre 1973. I've become aware of cockpit design issues with the 71/72 year causing irreparable cracks in the hull. This boat has a small cockpit with storage compartment, flanged edge. The mystery is that there's an aluminum channel at the cockpit/deck joint. There's also an aluminum edging around the gunwhales. Anyone have a clue as to what year this boat could be? Thanks for any help.
