BoatWiki - Databases


The Port State Information Exchange (PSIX) is a public data access system that is managed by the U.S. Coast Guard. It provides information derived from the Marine Information Safety and Law Enforcement (MISLE) database. This includes details about Coast Guard contacts with both domestic and foreign vessels operating in U.S. waters. It also provides information about current and previously documented vessels. It is updated on a weekly basis with current certificate of documentation issue dates.


The PSIX database is free of charge and can be accessed online by visiting the search link in the above WikiTags.

Search Criteria

This database can be searched by a vessel name, primary number, and hull number. On vessels without a name, the state registration number is sometimes substituted. The primary number field can be used for either the official documentation number or state registration number for non-documented vessels. It also facilitates searches for vessels based on when they were contacted by the US Coast Guard using variables such as vessel flag, classification society, vessel type gross tonnage and contact dates.

Search Results

PSIX search results are based on the variables provided. Multiple returns are possible and you can select the vessels of interest. This will provide more detailed information including vessel particulars and US Coast Guard contacts.


The PSIX database is not all inclusive and may be somewhat of a hit and miss proposition. The information provided is also very basic and lacking in detail. However it can help identify whether a vessel is documented or perhaps state registered. More comprehensive information can then be obtained by obtaining a vessel abstract of title or state boat registration record.
