A float plan is a short document that tells someone ashore where you are going, who is aboard, and when to worry. If you are overdue, it gives rescuers a description of the boat, a route to search, and a timeline, which can cut a search from days to hours. This guide gives you a copyable float plan template, explains each field, and shows how modern route planners generate and email one automatically.
- A float plan goes to a responsible person ashore, not to the Coast Guard.
- The essentials: boat description, people aboard, route with waypoints, departure and arrival times, and what to do if you are overdue.
- Close the plan when you arrive, otherwise you risk triggering a search for a boat that is tied up safely.
- The US Coast Guard Auxiliary publishes a printable form, and route planner apps can email a plan with your exact waypoints.
#What a float plan is, and who gets it
The float plan is held by a trusted person ashore: a spouse, a friend, a marina office. You do not file it with the Coast Guard; they have no system to hold routine float plans. Instead, your shore contact uses it to raise the alarm and hand rescuers everything they need if you do not check in on time. The US Coast Guard Auxiliary's Float Plan Central publishes the classic printable form if you prefer paper.
#The template
Copy this into a note or an email and fill it in before you leave. Short and complete beats long and half-filled.
- Vessel: name, type, length, hull color, engine, registration number, distinguishing features.
- People aboard: names, ages, phone numbers, relevant medical notes, and whether everyone has a lifejacket.
- Route: departure point and time, planned waypoints or route description, destination and expected arrival time, planned stops.
- Communications: phone numbers aboard, VHF channels monitored, tracker or share link if you have one.
- Safety gear: EPIRB or PLB, flares, raft or dinghy, first aid.
- Overdue instructions: "If you have not heard from me by [time], call [local emergency / coast guard number] and give them this plan."
#Filling it in well
The route section is where most float plans are weakest. "Heading up the coast" gives searchers a hundred miles of ambiguity; a waypoint list gives them a line to fly along. If you plan the trip in a route planner, your waypoints, distances, and ETAs already exist, so include them exactly. Our step-by-step route guide covers building that plan in the first place.
The most common float plan failure is forgetting to close it. Your contact assumes the worst, makes calls, and burns rescuer goodwill on a boat that is already in the slip. Set a reminder to send the "arrived safe" message the moment you tie up, and agree in advance on a grace period, for example one hour past ETA, before anyone escalates.
#Apps that build the float plan for you
Any route planner that knows your waypoints, speed, and departure time already holds 80 percent of a float plan. The Marine OS route planner turns a saved route into a printable float plan and can email it directly to your shore contact, with the vessel, speed, departure time, every waypoint with coordinates, per-leg distances and bearings, and a share link where they can watch progress on the chart. When you track your trip in Underway mode, that same link shows your position near-live.
Marine OS is marina management software, and our route planner for boaters generates float plans from your saved routes: print it, email it to a contact, and give them a live share link for the trip itself.
#Make it part of the routine
A float plan works best alongside the rest of the safety stack: an anchor alarm for the night, a tracking option so your contact can see progress instead of guessing, and a weather window chosen so the plan survives contact with the forecast.

Plan the passage in the Marine OS route planner, then print or email the float plan with waypoints, timings, and a live share link in a couple of clicks.
