Printable PDF Version of the Rules

Nav Rules Plus! includes a high resolution pdf version of the Navigation Rules, US Inland and International, which is an identical copy of the USCG publication. It can be printed for a sharp copy of the Rules, which is required to have onboard all vessels over 12 meters on Inland Waters. Needless to say, all vessels on all waters should have a hard copy of the Rules available at all times. This copy, like the original, includes all the Annexes and related documents.

Unlike the original, however, this one is fully searchable by word or phrase using our custom index we have built for it. Look up, for example, all references to "barge lights," or "sailing vessels," or find the single reference to the word "ice" in the Rules it is the only specific reference in the Rules to avoiding collisions with objects other than vessels.
