Greetings. I am new here so kindly bear patience with a senior with limited tech literacy. I am in search of owner information with which to contact a particular vessel (actually three of them) for the purpose of contacting to see if said vessel might be purchased. I have USCG Doc #'s and names of the boats, though they may of now changed. I've been to the USCG PSIX page but all it seems to be useful for is to verify the documentation as active. Am wondering if I need to employ the services of some sort of boat detective but I have never heard of such. In this 'info age' the information I require must be out there. Thanks for any assist.
