Emergency on the water in California

Life in danger, on any water: call 911 from a cell phone.
VHF 16
Channel 16 is the primary VHF-FM marine radio calling and distress channel. Carry a VHF radio on the coast and the Great Lakes.

Emergency and non-emergency contacts in California

911 for emergencies on all waters; on the ocean and bays, also call the U.S. Coast Guard on VHF-FM Channel 16.

Coast Guard sectors covering California

Each sector runs a 24-hour command center. Its line is useful for reporting an overdue boat or reaching the Coast Guard by phone, but in a distress use VHF Channel 16 or call 911 first.

California life jacket laws (and kids)

Children

Every child under 13 on a moving recreational vessel of any length must wear a USCG-approved life jacket. Exceptions: a child in an enclosed cabin, or tethered by a harness on a sailboat.

Source: dbw.parks.ca.gov

Everyone else, towing and seasonal rules

Kayaks, canoes and paddleboards of any length must carry one USCG-approved life jacket per person. Boats 16 ft and over must also carry one throwable device. Everyone being towed must wear a life jacket.

The federal baseline

Federal default: children under 13 must wear a USCG-approved life jacket on a recreational vessel that is underway, unless they’re below decks or in an enclosed cabin. Where a state has its own child-wear rule, the state rule applies on its waters (33 CFR 175.15(c), 175.25). Coast Guard required safety equipment →

Boater education card (the “California boating license”)

Most states don’t issue a boating license. What they require is a boater education card: proof you passed an approved boating safety course.

Who needs it

Since 1 Jan 2025, every operator of a motorized vessel, regardless of age. Exempt: operating under the direct supervision of a card holder aged 18+, and operating a rental vessel.

California jet ski (PWC) laws

Minimum age

16 to operate a boat with a motor over 15 hp (includes most PWC) alone; ages 12-15 only with an adult 18+ on board

Rules on the water

Everyone on a PWC must wear a USCG-approved life jacket; attach the engine cut-off lanyard to your body; no PWC operation from sunset to sunrise, even with navigation lights; anyone towed must wear a life jacket and an observer aged 12+ is required when towing.

Kayak, canoe, paddle board and kite rules

Paddleboards, kayaks and canoes count as human-powered vessels: each must carry a USCG-approved life jacket, and children under 13 must wear one while underway. Many lakes and reservoirs have local rules (some ban PWC or two-stroke engines). No statewide kiteboarding rule found.

Boat registration in California

Register with the California DMV: all motorized vessels of any size and sailboats over 8 ft. Exempt: canoes, kayaks, rowboats and other paddle/oar-powered boats, and sailboats 8 ft or less without a motor. Motorized boats used in fresh water must also display a Quagga/Zebra Mussel Fee sticker.

WHAT VESSELSOS DOES HERE

VesselSOS on California waters

  • Life in danger? One tap dials 911. The screen shows your GPS position and a word-for-word script: say “Boat emergency, I’m on the water” and the name of the lake, river or bay you’re on.
  • On the coast and the Great Lakes it also shows which Coast Guard sector covers your position, with that sector’s 24-hour line as a second Call button, and a VHF Channel 16 MAYDAY script filled with your boat’s details for you to read on your own radio.
  • A live link for family ashore (Plus, free during the beta): your position, speed, course and phone battery in any browser, no app needed on their end. You send it by text yourself.
  • Not an emergency? The tow screen has Call buttons for the TowBoatUS and Sea Tow 24-hour dispatch lines, or your own member number.

What it doesn’t do: it doesn’t call the Coast Guard for you and isn’t connected to 911 or any rescue system. Nobody is alerted automatically if you’re late. The return-time check only asks “Are you OK?” on your own phone. It doesn’t replace a VHF radio, a PLB or EPIRB, or the life jackets the law requires.

iPhone only, in invite-only TestFlight beta. Not in the App Store yet, no Android. US support (911 routing, American English) is in beta version 1.4 and later.
