A good boat trip runs on five decisions made before you leave the dock: where you are going, which way and when, what the weather will allow, whether the fuel and food math works, and who ashore knows the plan. This boat trip planner walks the five in order, with the numbers that make each one easy and the tools that do the arithmetic for you.
- Pick the destination by time budget: half your hours out, half back, with a fifth held in reserve.
- Plan the route as waypoints with a distance and ETA, not as a direction and a hope.
- Check wind, gusts, and wave period for the whole window, including the ride home.
- Fuel: hours underway times burn rate, then keep a third in reserve.
- Send a float plan and a live share link to someone ashore, every trip.
#Step 1: pick a destination that fits the day
Work backwards from hours. With 8 hours and a 20-knot boat, your comfortable radius is about 60 to 70 nautical miles: three hours out, three back, and two in hand for the anchorage, the swim, and the slow harbor miles. A 6-knot sailboat with the same day has a 20-mile radius. Guides to how far a boat travels in a day cover the ranges by boat type, and published sea distances settle the argument about how far that harbor really is.
#Step 2: route and timing
Turn the plan into waypoints with distances and ETAs: departure, any turns or hazards, the destination, and the alternates. This is ten minutes in a route planner and it converts "we should be back by six" into arithmetic. The method is in how to plan a boat route; in tidal waters, timing the shallow spots matters more than the course, so note the tide at your arrival times.
#Step 3: the weather window
Check the forecast for the whole window, not the departure hour: the afternoon sea breeze and the ride home are where day trips go wrong. Read gusts and wave period alongside wind speed, and if the timing is flexible, compare leaving times instead of forecasts: a departure scanner rates every window along your actual route. The full method is in the weather window guide.
#Step 4: fuel, food, and margins
Fuel is hours underway times your burn rate, with a third of the tank held in reserve, the arithmetic is in the fuel consumption guide. Water at a liter per person per hour in summer, food that survives a cooler, and sun cover round out the list. The margin rule from passage planning applies to day trips too: plan 80 percent of what the math allows.
#Step 5: float plan and live sharing
Tell someone ashore where you are going, who is aboard, and when to worry: a float plan takes two minutes and is the cheapest safety equipment there is. Modern planners email it automatically and add a live share link so the person ashore watches the dot move instead of calling you hourly. Run the safety checklist while the coffee brews and you are gone.
The Marine OS route planner covers steps 2 through 5 in one place: waypoints with ETAs from your boat's speed, per-leg fuel from your burn rate, weather and comfort ratings along the route, a 72-hour departure scan, an emailed float plan, and a live share link for the trip itself. Step 1 stays yours: it is the fun part.
Marine OS is marina management software, and the Marine OS app includes the route planner described above for boaters, alongside destination marina lookup for the harbor at the end of the trip.
