Nautical Numbers

Plan a multi-port voyage day by day. Set arrival and departure times in each port, add navigation days, and see the speed needed on every leg.

Route options
    Each row is one day. Use ☾ on a port to stay overnight; the departure time then moves to the last day of the stay. Leg speeds use the time from departure in one port to arrival in the next, with 24 hours for every navigation day in between. Distances follow a standard shipping-lane network and are planning estimates. Route network from Eurostat SeaRoute (via the searoute project); ports from UN/LOCODE; coastlines from Natural Earth.
