We are interested in purchasing a Catalina 400 and have identified one that we think might suit us. We received a fax of the Certificate of Documentation, issued by the National Vessel Documentation Center, from the broker. It lists as restrictions: "No Coastwise; build evidence not presented" and "No Fishery; build evidence not presented." I note that in the "Place Built" space, the response provided is "unknown." Can anyone enlighten us on what the restrictions mean and if/how they might be removed? Thus far we have been unable to get a hull# from this broker although this certificate does have an official number and an IMO. Might the hull# be embedded in one of these? The Year Completed is also listed as "unknown" on this document, even though it is listed as a 1996 boat. Thanks,Marianne
