Harbor regulations - The harbor is administered by the Marine Department, Ventura County Property Administration Agency, and is under the control of a harbormaster, who has an office on the E side of the harbor about 400 yards N of the first bend in the channel.  The harbor office maintains guest berths for 70 craft.  Transients should report to the harbormaster for berth assignments.  The harbormaster guards VHF-FM channel 16 24 hours a day.  Harbor patrol boats operate from the office.

The Channel Islands Harbor Patrol is on duty 24 hours per day, 365 days per year. The Channel Islands Harbor Patrol is responsible for all of the inland waterways of the Channel Islands Harbor and open state waters; one mile north and south, and one mile seaward of the detached breakwater. The Channel Islands Harbor Patrol will respond out of our area for life-threatening emergencies.
The office is located on the starboard side of the main channel as you enter the Harbor, just past the Coast Guard Station. If you are in the area, they would be happy to provide you with information regarding the Harbor or its operation.
