Anyone aware of this program?  You can run a search per cruise line or for a specific ship.  I was looking at one particular ship that had inspection reports online from 1996 forward.

In case you aren't familiar... "The Vessel Sanitation Program (VSP) at the Centers for Disease Control and Prevention (CDC) assists the cruise ship industry to prevent and control the introduction, transmission, and spread of gastrointestinal (GI) illnesses on cruise ships. VSP operates under the authority of the Public Health Service Act (42 U.S.C. Section 264 Quarantine and Inspection Regulations to Control Communicable Diseases)." (CDC website)
