Multi-Leg Voyage Distance Builder
Chain ports into a voyage — per-leg sea-route distances and transit times, summed for the whole trip.
Each leg is routed over an open maritime network (channels, canals and chokepoints included). A planning estimate only: real distances and times vary with vessel, weather, congestion and routing choices. Not a voyage plan.
How it works
Per-leg sea routes, one voyage total.
Up to eight ports
Add, remove and reorder port calls across a 5,966-port index. Each leg uses a modelled sea route where the network covers it — a printed NGA Pub. 151 figure or labelled straight-line estimate otherwise.
Shareable voyage
The port sequence is written into the page URL, so the Copy link button shares this exact voyage — anyone opening it sees the same legs and the same total.
Planning estimate
Routing-model distances, not a voyage plan. Real distances vary with vessel, weather and routing choices — operational planning is what Voyage Intel Pro is built for.
