Far Enough: Boat Fuel Planner

sdk1

About this app

Far Enough is the marine fuel planner that answers the one question that matters before you leave the dock: will you make it back — with fuel to spare?

Enter your boat once — tank size, cruise speed, and burn rate — and Far Enough turns every trip into a clear go / no-go. See exactly how much fuel you'll burn, what it'll cost, and how much reserve you'll have left when you tie up.

PLAN WITH CONFIDENCE
• Live range rings on a nautical chart — how far you can go on the fuel aboard, plus a reserve-intact ring
• Speed-aware estimates — faster burns more fuel, and Far Enough knows the difference
• Sea-state aware — headwind and chop are baked into the estimate, not ignored
• Round-trip math done right — there and back, with reserve

KNOW YOUR REAL NUMBERS
• Self-calibrating burn — log a fill-up and the app learns your boat's true gallons-per-hour over time
• Log the price you actually paid at each fill-up, so cost estimates use your real numbers
• Set fuel aboard anytime — no refuel logging required
• Trip history — name, favorite, and revisit every run

A REAL SHIP'S LOG
• A passage log the way paper log books do it — ports, times, positions, engine hours, and fuel for every leg
• One-tap capture of position, engine hours, and fuel when your boat's network is connected
• Export the whole log as CSV, or any trip as GPX

LIVE FROM THE BOAT NETWORK
• Connects to your NMEA 2000 network through a SignalK gateway over onboard Wi-Fi
• Live fuel level, speed, and engine data right on your dashboard
• Completely optional — everything works without it

LIVE MARINE CONDITIONS
• Real wind and swell for your home port, right on your dashboard
• So the sea state behind your estimate isn't a guess

FLOAT PLAN, DONE RIGHT
• Fill in crew, departure, shore contact, and vessel details
• Send a proper float-plan PDF (or a quick text) so someone ashore has your route, ETA, and fuel margin if you're overdue
• An overdue reminder fires if you haven't closed out your plan by your return time

BUILT TO RESPECT YOU
• One-time purchase — no subscription, ever
• No account, no sign-up — your boat and trips stay on your device
• Back up everything to a file you control, and restore it on a new phone
• No ads, no analytics, no tracking

Far Enough works for center consoles, cruisers, sailboats under power, and just about anything with a fuel tank and a throttle. Plan smarter. Run farther. Get home with margin to spare.
