I've recently been sent a link from a complete stranger, to a 53ft Colvin for sale in Florida. It's on that 'Cruisers' Forum' and I suspect you might have to sign up to find out more - clicking on his name didn't let me make contact. But I did note that he had only posted twice, so suspect he joined in order to sell the boat!
The boat would appear to have been used as a charter vessel, so should be in first-class condition and at $44,000 seems very reasonably priced. You could buy the business, too, if you fancy! Not much more information, I'm afraid.
