Colregs Demarcation Lines - The lines established for Channel Islands Harbor are described in 80.1122, chapter 2.
Channels - The entrance to Channel Islands Harbor is between two jetties protected by an offshore breakwater. Each end of the breakwater and both the seaward and inshore ends of both jetties are marked by lights. A fog signal is at the seaward end of the S jetty.
The area SE of the entrance is subject to rapid and uncertain shoaling. Mariners should exercise caution when approaching the harbor from the S, especially at night.

The harbor office has a limited number of guest slips. Transients should report to the harbormaster for slip assignments. The harbor patrol monitors VHF-FM channel 16, 24 hours a day.
Supplies - Gasoline and diesel fuel are pumped at a fuel dock on the E side of the harbor just N of the harbor office. Water, ice, snacks and limited marine supplies are available at the fuel dock.
Repairs - Two full-service boat yards are located on the E side of the channel, about .5 mile N of the harbor office.
