There is a guy who does the lifts at our marina, his name is Jimmy Black, but I don't know his company name. He may be someone worthy of getting in touch with. I think we have close to a dozen lifts on our dock.
If you have some time give our marina a shout and ask them if they can put you in touch with him, ask for Eddie or Brett and tell them "Frank with the Apache" referred you. 732-842-3700
