SeaWise is the voyage planning calculator app built for captains and fleet managers who make decisions based on data — not guesswork. Plan any passage with exact nautical distances, live bunker fuel prices, AI-generated sea routes, and accurate fuel burn calculations. Everything you need to budget a voyage, brief a crew, or manage a fleet — in one place. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ --- LIVE GLOBAL BUNKER PRICES Stop hunting across broker emails and outdated spreadsheets. SeaWise pulls live MGO, VLSFO, and HFO prices from major bunkering ports worldwide — Rotterdam, Singapore, Fujairah, Gibraltar, Las Palmas, Houston, Panama, Miami, and more. See the current fuel costs at your departure port, your destination, and every stop in between. Updated continuously so your budget reflects the actual market, not last week's numbers. --- ACCURATE PORT-TO-PORT DISTANCES SeaWise calculates nautical mile distances between global ports using the Haversine formula — the same method used in professional maritime navigation. Not straight-line estimates. Not road distances repurposed for sea. Real routes. Real distances. --- AI-POWERED SEA ROUTE PLANNING SeaWise generates intelligent sea routes that follow recognised shipping lanes, account for major straits and waypoints, and avoid routing you over land. Get a full waypoint-by-waypoint route for any ocean passage in seconds. Whether you're planning a Med season, a transatlantic crossing, or a Caribbean circuit — SeaWise maps it out. --- FUEL CONSUMPTION CALCULATOR Input your vessel's fuel curve — consumption rate at different engine speeds — and SeaWise calculates your total fuel burn for any voyage. See burn in litres or metric tonnes. Apply live bunker prices to get your total fuel cost in USD. Adjust speed to model the cost difference between a fast passage and an economical one. For a 50m motor yacht burning 200L/hr, the difference between 14 knots and 12 knots can mean 30–40% less fuel on a long passage. SeaWise shows you exactly what that saving is worth. --- COMPLETE VOYAGE COST ESTIMATES Combine distance, fuel burn, live market prices, and passage time into a single voyage cost report. Ideal for: • Charter budget preparation • Owner voyage approval • Fleet manager cost tracking • Captain passage planning Export your calculation as a clean summary — ready to drop into a crew brief or send to an owner. --- BUILT FOR PROFESSIONALS SeaWise is used by yacht captains, superyacht management companies, and fleet operators managing vessels from 30 to 100+ metres. 50,000+ routes calculated. 200+ global ports covered. Trusted across the Mediterranean, Caribbean, Pacific, and Atlantic circuits. --- SIMPLE, TRANSPARENT PRICING One plan. All features. No paywalls inside the app. $9.99/month or $99/year (save 17%). Cancel any time. No contracts. --- SeaWise won't navigate your vessel. But it will make sure you arrive at the right financial decision before you leave the dock. Download SeaWise and plan your next voyage with confidence.
