The Port State Information eXchange (PSIX) is an underutilized tool available to marine operators. If owners or operators have vessel specific questions, we encourage you to take a look at PSIX. The Port State Information eXchange (PSIX) system contains vessel specific information derived from the United States Coast Guard’s Marine Information Safety and Law Enforcement System (MISLE). The information contained in PSIX represents a weekly snapshot of Freedom of Information Act (FOIA) data on U.S. flag vessels, foreign vessels operating in U.S. waters, and Coast Guard contacts with those vessels. Information on unclosed cases or cases pending further action is considered privileged information and is not displayed in the PSIX system. For customers that would like to link information directly from PSIX to their respective websites, PSIX supports eXtensible Markup Language (XML). Information concerning PSIX XML functionality can be found at:

PSIX also contains information about Coast Guard approved equipment, accepted laboratories, and liferaft servicing facilities via direct link to the Coast Guard Maritime Information Exchange (CGMIX) website.
