U.S. Coast Guard - So-Cal Boating Resources

Help them help you provide a safe and fun time on the water.

Southern California operations fall under the U.S. Coast Guard Eleventh District (D11). The region is divided primarily into two major operational sectors covering maritime safety, search and rescue, law enforcement, and environmental protection:

Major Sectors & Stations

Sector Los Angeles – Long Beach (LA/LB)
- Coverage: Central SoCal coast (Morro Bay south to San Mateo Point, including the Channel Islands).
- Headquarters: Terminal Island, San Pedro, CA.
- Key Units & Small Boat Stations:
  - Station Los Angeles / Long Beach (San Pedro)
  - Station Channel Islands Harbor (Oxnard)
  - Station Morro Bay
  - Air Station Ventura / Point Mugu
Sector San Diego
- Coverage: Southernmost SoCal coast (San Mateo Point south to the U.S.–Mexico border, plus inland waters like the Salton Sea and Colorado River).
- Headquarters / Air Station: Harbor Island, San Diego, CA.
- Key Units & Small Boat Stations:
  - Station San Diego
  - Cutter Fleets (Fast Response Cutters and Patrol Boats assigned to regional maritime boundary security)

Key Operational Contacts

Emergencies / Search & Rescue (24/7):
- VHF Radio: Channel 16 (156.8 MHz)
- Sector LA/LB Command Center: (310) 521-3801
- Sector San Diego Command Center: (619) 278-7000
Local Broadcast Notice to Mariners (BNTM): Broadcast regularly on VHF Channel 22A for local marine hazards, weather warnings, and safety zones.

Float Plan Complete this plan before you go boating and leave it with a reliable person who can be depended upon to notify the Coast Guard, or other rescue organization.

A float plan is a written operational log left ashore before heading out on the water. It contains a detailed breakdown of your vessel, passengers, onboard safety equipment, planned route, and expected return time.

Think of it as an insurance policy for search and rescue (SAR): you never file it directly with the U.S. Coast Guard. Instead, you leave it with a trusted person on land—a “holder”—who acts as your emergency trigger if you become overdue.

Why It Is Critical in an Emergency

When a vessel founders, loses power, or suffers an onboard medical emergency outside cellular coverage, the crew’s ability to call for help can be cut off instantly. In those scenarios, a float plan is often the only mechanism that alerts authorities that you are missing.

Eliminates Delays: Without a float plan, family members might wait until morning or the next day to report a missing boat because they aren’t sure of the exact schedule. A float plan sets a hard, non-negotiable threshold for when to alert authorities.
Shrinks the Search Grid: Ocean and coastal search areas expand exponentially as time passes due to winds and currents. By documenting your exact departure point, destination, waypoints, and cruising speed, SAR controllers can calculate drift vectors and narrow down a search grid from thousands of square miles to a targeted corridor.
Informs Rescue Assets: Knowing whether you have an EPIRB/PLB, flares, a VHF radio, or a life raft dictates how the Coast Guard or local marine units approach the rescue mission.
Identifies the Rig: Detailing your vessel’s hull color, engine type, registration numbers, and tow vehicle parked at the ramp allows marine safety officers to confirm at the marina whether your vessel is still out on the water.

What a Complete Float Plan Must Include

A comprehensive float plan should cover six main categories:

Vessel Description: Make, model, length, hull color, trim, deck color, vessel name, and registration/official numbers.
Propulsion & Fuel: Engine type (inboard/outboard/gas/diesel), horsepower, fuel tank capacity, and estimated range.
Passenger Manifest: Names, ages, emergency contact numbers, and any critical medical conditions or medications for every person aboard.
Safety & Comms Equipment: Presence of VHF radios (and call sign/MMSI), handheld radios, cell numbers, EPIRB/PLB hex IDs, visual distress signals (flares, orange flags), life jackets, sound signals, and life rafts.
Route Details: Departure marina/ramp, date and time of departure, intended destinations or fishing spots, planned waypoints, expected cruising speed, and final return location.
Tow Vehicle Data: License plate number, make, model, color, and location of the vehicle and trailer parked at the launch ramp.

How to Use a Float Plan as an Effective Safety Tool

1.Fill Out the Plan Before Every Trip:Never skip this step for ‘short’ runs.

Complete the float plan prior to untying lines—even for routine day trips or coastal runs. Conditions change rapidly, and short trips carry the highest rate of complacency.

2.Designate a Reliable Shore Contact:Select someone who understands their responsibility.

Entrust the plan to a dependable friend, spouse, or marina operator. Ensure they understand that they are the primary safety monitor for your voyage.

3.Establish a Strict ‘Drop-Dead’ Overdue Time:Define the threshold between ‘delayed’ and ’emergency’.

Set an Overdue Time (e.g., 2 hours past scheduled return). Explicitly instruct your shore contact: “If you have not heard from me by 20:00, contact the Coast Guard Command Center or local Sheriff’s Harbor Patrol.”

4.Maintain Active Communication:Update your contact if plans change on the water.

If weather forces a detour, or if you decide to stay out past your scheduled return time, contact your holder immediately via cell or satellite messenger to update the plan.

5.Formally Close the Plan Upon Return:Prevents false SAR deployments.

As soon as you return to the marina or tie up at the dock, contact your shore holder to close out the plan. Unclosed float plans trigger unnecessary searches that tie up critical rescue assets.

Quick Reference: Emergency Action Steps for Your Holder

Make sure your designated shore contact has these steps printed directly on the float plan:

Step	Action	Details
1. Attempt Direct Contact	Call/text the vessel operator and passengers	Try cell phones, satellite messaging, or harbor VHF monitor if nearby.
2. Verify Location	Check the launch ramp / marina	Confirm if the tow vehicle and trailer are still parked at the ramp.
3. Contact Authorities	Call USCG Command Center or 911	Provide the Coast Guard or local authorities with the full float plan document.
