Sea Route Calculator – Port to Port Distance & Voyage Time

SeaRoutesNav calculates the sea distance and estimated voyage time between any two ports worldwide. Pick an origin and destination, set your vessel speed, and the tool builds a realistic maritime route on the map with Suez, Panama, Gibraltar and Kiel canal options taken into account. It then returns the distance in nautical miles, the sailing duration and an estimated time of arrival.

It's built for ship operators, chartering and freight teams, and anyone planning a voyage who needs a fast port-to-port distance and ETA without spreadsheets or manual great-circle math. Results update instantly as you change speed or canal routing.
