A regulated navigation area is a water area within a defined boundary for which regulations for vessels navigating within the area have been established under this part.

Each District Commander may control vessel traffic in an area which is determined to have hazardous conditions, by issuing regulations:

(a) Specifying times of vessel entry, movement, or departure to, from, within, or through ports, harbors, or other waters;

(b) Establishing vessel size, speed, draft limitations, and operating conditions; and

(c) Restricting vessel operation, in a hazardous area or under hazardous conditions, to vessels which have particular operating characteristics or capabilities which are considered necessary for safe operation under the circumstances.

(a) The master of a vessel in a regulated navigation area shall operate the vessel in accordance with the regulations contained in Subpart F.

(b) No person may cause or authorize the operation of a vessel in a regulated navigation area contrary to the regulations in this part.
