AUTHORITIES: Hydrography and topography by the National Ocean Service, Coast Survey, with additional data from the Corps of Engineers, Geological Survey, and U.S. Coast Guard. NOTE A: Navigation regulations are published in Chapter 2, U.S. Coast Pilot 7. Additions or revisions to Chapter 2 are published in the Notice to Mariners. Information concerning the regulations may be obtained at the Office of the Commander, 11th Coast Guard District in Alameda, California or at the Office of the District Engineer, Corps of Engineers in Sacramento, California. Refer to Code of Federal Regulations section numbers. NOTE C: The U.S. Coast Guard operates a mandatory Vessel Traffic Services (VTS) system in the San Francisco Bay and surrounding areas. Vessel operating procedures and designated radiotelephone frequencies are published in 33 CFR 161, the U.S. Coast Pilot, and/or the VTS User's Manual. The entire area of the chart falls within the Vessel Traffic Services (VTS) system. WARNING – PRUDENT MARINER: The prudent mariner will not rely solely on any single aid to navigation, particularly on floating aids. See U.S. Coast Guard Light List and U.S. Coast Pilot for details. SUPPLEMENTAL INFORMATION: Consult U.S. Coast Pilot 7 for important supplemental information. CAUTION: Small craft should stay clear of large commercial and government vessels even if small craft have the right-of-way. All craft should avoid areas where the skin divers' flag, a red square with a diagonal white stripe, is displayed. CAUTION: Temporary changes or defects in aids to navigation are not indicated. See Local Notice to Mariners. CAUTION - WARNING CONCERNING LARGE VESSELS: The "Rules of the Road" state that recreational boats shall not impede the passage of a vessel that can navigate only within a narrow channel or fairway. Large vessels may appear to move slowly due to their large size but actually transit at speeds in excess of 12 knots, requiring a great distance in which to maneuver or stop. A large vessel's superstructure may block the wind with the result that sailboats and sailboards may unexpectedly find themselves unable to maneuver. Bow and stem waves can be hazardous to small vessels. Large vessels may not be able to see small craft close to their bows. RADAR REFLECTORS: Radar reflectors have been placed on many floating aids to navigation. Individual radar reflector identification on these aids has been omitted. SUBMARINE PIPELINES AND CABLES: Additional uncharted submarine pipelines and submarine cables may exist within the area. Not all submarine pipelines and submarine cables are required to be buried, and those that were originally buried may have become exposed. Mariners should use extreme caution when operating vessels in depths of water comparable to their draft in areas where pipelines and cables may exist, and when anchoring, dragging, or trawling. Covered wells may be marked by lighted or unlighted buoys.

The range of reception is variable, but for most stations is usually 20 to 40 miles from the antenna site, but can be as much as 100 nautical miles for stations at high elevations. Mt. Pise, CA KHB-49 162.40 MHz 24 hours daily Mt. Umunhum, CA KEC-49 162.55 MHz 24 hours daily WWF-64 162.45 MHz 24 hours daily Sacramento, CA KEC-57 162.55 MHz 24 hours daily RULES OF THE ROAD (ABRIDGED): Motorless craft have the right-of-way in most cases. Sailing vessels and motorboats less than sixty-five feet in length, shall not hamper, in a narrow channel, the safe passage of a vessel which can navigate only inside the channel. A motor boat being overtaken has the right-of-way. Motorboats approaching head to head or nearly so should pass port to port. When motorboats approach each other at right angles or obliquely, the boat on the right has the right-of-way in most cases. Motorboats must keep to the right in narrow channels, when safe and practicable. Mariners are urged to become familiar with the complete text of the Rules of the Road in U.S. Coast Guard publication "Navigation Rules."
