Find Nearby Safe Harbor During Boating Emergencies
The Emergency Safe Harbor Finder is a one-tap tool for boaters in trouble. It reads your live GPS position from the device you are already holding, surfaces the closest marina, fuel dock, and protected harbor, and gives you the U.S. Coast Guard, 911, and BASRA numbers in a single tap. Use it the moment something feels wrong — engine trouble, taking on water, weather collapse, a medical event onboard, low fuel, or a rapidly building sea state you cannot safely punch through.
Before you turn for shelter, weigh the practical factors. Distance to the nearest harbor is only useful if you have the fuel and the daylight to reach it. A closer marina with a difficult inlet may be worse than a slightly farther port with a wide, well-marked channel. Tide stage matters: many ICW and barrier-island marinas dry out at low water, and inlet bars can break dangerously on an outgoing tide against onshore wind. Storm direction and sea state should drive which side of an island or peninsula you commit to. When in doubt, transmit a PAN-PAN on VHF 16 and ask the Coast Guard for guidance — they will route you to the right harbor.
Once you have a target harbor, call the dockmaster on VHF 16 or by phone before arrival. Confirm depth, slip availability, fuel hours, and whether they can accept a vessel in distress. Share your live position with shore contacts using the share button so someone ashore is tracking your run. If conditions deteriorate, escalate immediately — a Mayday on Channel 16 brings the full Coast Guard response.
Plan ahead and you will never need this page in anger. Browse boating safety resources, study the hurricane-protected harbors on our waterway pages, review the full maritime emergency directory, and use the rest of our AI boating tools to pre-stage fuel stops and weather windows on every route you plan.
Safety reminder: in a life-threatening situation, call 911 or the U.S. Coast Guard on VHF 16 first. This tool is an aid, not a substitute for the marina, dockmaster, or emergency services on the other end of the radio.
FAQ
When should I divert to a safe harbor?
Any time a problem is growing faster than you can fix it — weather, mechanical, medical, or fuel. Earlier is safer; do not wait for the situation to become an emergency.
What should I say on VHF Channel 16?
State vessel name three times, position, persons onboard, and the nature of the emergency. Use Mayday for life-threatening, PAN-PAN for urgent but not life-threatening.
Does this tool work without internet?
GPS works without internet, but the marina and fuel dock lookups need a signal. Save the USCG number (1-877-249-2837) and your float plan before you leave the dock.
