The Harbor Master CD-ROM comprises all commercial vessels registered with the US Coast Guard and addition to recreational boats which are registered with the environmental police. The CD-ROM covers all 50 states and is now available for the nation’s seaport authorities. The Worldwide Harbor Master CD-ROM's, unlimited search capabilities allows the investigator to search a wider range of vessels and increases coverage from state to state. The portability of the CD-ROM, combined with unlimited, real-time access to search partial information, provides a tremendous technology asset towards helping with maritime safety and security. Some of the common searches are vessel size range, vessel weight range, as well as a combination of both along with partial name. You can also search by partial name and surrounding cities and states, and so much more. The CD-ROM focuses on producing this software solution for port authorities to have a tool for anti-terrorism and harbor security.
