Maritime chokepoints

Canals and straits concentrate most of global container traffic. Explore each chokepoint, its key facts and the routes that depend on it.

Frequently asked questions

How are these sea distances calculated?

Distances are computed with searoute, an open-source routing engine that follows real commercial shipping lanes, instead of a simple straight-line (great-circle) measure. This mirrors the path vessels actually sail, including canals and straits.

What is the difference between nautical miles and kilometers?

One nautical mile equals 1.852 kilometers. Maritime distances are expressed in nautical miles because one nautical mile corresponds to one minute of latitude, which makes navigation calculations easier.

How do I estimate the transit time between two ports?

Divide the distance in nautical miles by the vessel speed in knots to get hours at sea. Container ships typically cruise at 14 to 18 knots; each route page includes a ready-made speed table plus port and chokepoint details.
