Frequently Asked Questions

What is SeaWise?

SeaWise is a port-to-port distance and fuel consumption calculator built for maritime professionals. Enter your origin and destination ports, configure your vessel's speed and fuel burn rate, and get precise calculations for distance (nautical miles), fuel consumption (liters or gallons), estimated travel time, and total voyage cost. It also includes AI-powered sea route generation and a global fuel price tracker.

How accurate are the distance calculations?

SeaWise uses AI-powered route generation with Google Search grounding to plot realistic maritime routes that follow established shipping lanes, navigate through straits and canals, and avoid land. Distance is calculated using the Haversine formula along the generated waypoints, giving you nautical mile accuracy that reflects actual sailing routes rather than straight-line estimates.

How does AI route planning work?

When you enter origin and destination ports, our AI analyzes the route and generates maritime waypoints that follow real shipping lanes. It accounts for major chokepoints like the English Channel, Strait of Gibraltar, Suez Canal, Malacca Strait, and Panama Canal. The AI uses Google Search grounding to access real geographic data, ensuring waypoints stay on navigable water.

What devices is SeaWise available on?

SeaWise is available as a web app accessible from any modern browser at app.seawise.site. Native iOS and Android apps are coming soon to the Apple App Store and Google Play Store. Your data syncs seamlessly across all your devices via cloud storage.

How do I track fuel prices?

The Global Fuel Market feature tracks bunker fuel prices at major ports worldwide including Rotterdam, Singapore, Fujairah, Houston, Gibraltar, Panama Canal, and Miami. Prices are updated via AI-powered sync that pulls the latest rates from global fuel suppliers. You can view prices per liter or per gallon, compare across ports, and factor live pricing into your voyage cost estimates.
