The classic boat day has a shape everyone recognizes: top up at the fuel dock, run to the sandbar while the water is glassy, waterfront lunch when the family gets hungry, a swim anchorage for the afternoon, home before the seabreeze chop and the sunset glare. Five stops. The families that come home relaxed and the families that come home fried at 7 pm usually visited the same places - in a different order. This is the guide to building a day-trip itinerary that flows: sequencing, timing, and the fuel math, plus how to compute the order instead of arguing about it at the helm.
- A five-stop day has 120 possible orders if everything is flexible; picking by vibe routinely adds an hour of running time.
- Two stops fix themselves: fuel is first (full tank, short queue in the morning) and home is last. Optimize what is between them.
- Time-of-day beats geography for two stops: sandbars want morning glass and low-ish tide, west-facing runs home want to happen before sunset glare.
- Budget the clock honestly: every stop costs 20-40 minutes beyond the running time - dock lines, anchor sets, "five more minutes" at the sandbar.
- Compute the order over real water distances; a bay with a spit of land in it makes straight-line guesses wrong.
#The skeleton: what is fixed, what floats
Start every day-trip plan by splitting stops into fixed and flexible. Fuel is effectively fixed first: you want the full tank at the start, the morning queue is shortest, and nothing ruins an afternoon like detouring to fuel mid-day. Home is fixed last. A lunch reservation is fixed in time (13:00) but its position in the route order depends on where the morning takes you. The sandbar and swim anchorage are flexible - they go wherever they make the loop shortest, subject to one big exception: conditions.
The exception matters. Sandbars are a morning stop almost everywhere: the water is calm before the seabreeze fills in, the crowd is thinner, and a mid-tide arrival keeps the approach honest. An exposed swim spot with an afternoon fetch becomes a rolly mess by 15:00. So the real method is: fix fuel first and home last, pin the timed stops, give conditions a vote on when the sandbar happens, and then let the ordering of what remains be a pure distance question.
For every stop, add 30 minutes to whatever the running time says: fenders and lines at a dock, two tries at an anchor set, the dinghy shuttle, the goodbye lap at the sandbar. A five-stop day carries about 2.5 hours of non-running time. If the running math plus stop overhead passes 9 hours, cut a stop - the last one you added, not the one everyone came for.
#A worked day
Marina on the west shore of the bay; fuel dock two miles north; sandbar on the northeast shoal; lunch dock southeast across the channel; swim anchorage tucked south. Typed in the order the family suggested them - sandbar, lunch, swim, fuel, home - the boat crosses the bay four times and gets fuel at the worst moment. The computed order - fuel, sandbar, lunch, swim, home - is one clockwise arc: every leg short, morning glass at the sandbar, lunch at the dock at noon, the protected anchorage during the windy hours, and a downwind run home. Same five stops. The zigzag version runs about half again as far and puts the longest leg into the afternoon chop.
The Marine OS route planner automates the distance half of this. The Multi-Stop Optimizer takes up to eight stops - searched by name or pasted as coordinates - and returns the visiting order with the least total water distance as one editable route, round trip or one-way, with the miles saved versus your typed order shown next to the result. The Voyage Timeline then stamps an ETA and a wind and wave forecast on each stop, which is where you catch the "sandbar at 15:00 in 15 knots" problem before it happens. Fuel burn for the whole loop comes from your boat's gallons-per-hour in the route summary.
Marine OS is marina management software, and its route planner includes a Multi-Stop Optimizer (best order for up to 8 stops over real water distances) and a Voyage Timeline (ETA plus forecast at each stop) so a five-stop family day gets planned in minutes. Part of Boater Pro.
