crane launching a mariner centerboard model

[paul DeMay]

Does anyone have information on launching a Mariner 2+2, 1970. centerboard model from a crane? Club stores boats on trailers. You can launch by boat ramp, or by crane. I have seen information on the fixed keel model, but what about the centerboard model? Is it possible? Details on sling, and location of supports on boat?

Never had any luck

I have tried several times, unsuccessfully. I have exactly the same boat, and it's just too bow-heavy for slings. I was told that the obvious spots for supports for a harness wouldn't hold.In the meantime, I'm looking for a hatch for this boat - mine blew off and is floating down the Hudson. Any suggestions? you can reach me at dprouty@uniteunion.org
