Not sure, but one would think, if a marina has foreclosed, and the marina is a government agency, that 'SHOULD" clear the title right there and then, no different than a bank foreclosing on a home, car etc. Any previous owner(s) lose any and all interest in the boat in this instance. My marina sells one or two boats a year. Some look reasonable, others......
She drives me boat,
I drives me dinghy!
