Charleston to Mombasa shipping route.

Ships leaving Charleston for Mombasa head east and cover a sea distance of 8,656 nautical miles (16,031 km), via Suez Canal. The straight line between the ports is 13,000 km; coastlines and shipping lanes add the rest. On the way the vessel passes Strait of Gibraltar, Bab-el-Mandeb and Suez Canal, so canal transit fees and waiting time at the canal are part of every voyage.

Shipping time depends on speed. At 14 knots, a common container ship service speed, the passage takes 25.8 days at sea. Slow steaming at 12 knots stretches it to 30.1 days, while 18 knots brings it down to 20.0. Container transit time on a liner service is longer than the steaming time: ships call at other ports on the rotation, and cargo may transship at a hub. Add terminal time at Charleston and Mombasa to plan the full ocean transit time.

Red Sea security changes the sea distance on this lane. A ship sent via Cape of Good Hope sails 9,441 nm instead of 8,656 nm and spends roughly 2.3 extra days at sea. Ask your forwarder which routing the carrier uses: the booking price and the arrival date both depend on it.

2,441 nm of the route, 28% of it, lies inside North American ECA and Mediterranean Sea ECA. In an emission control area ships must burn fuel with no more than 0.1% sulphur or clean the exhaust with scrubbers. That fuel costs more, and carriers add it to the ocean freight bill as a low sulphur or ECA surcharge.

Container freight rates on Charleston to Mombasa move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one.
