Gdansk to Charleston shipping route.

Ships leaving Gdansk for Charleston head north west and cover a sea distance of 4,302 nautical miles (7,968 km), on a direct course. The straight line between the ports is 7,613 km; coastlines and shipping lanes add the rest. No canals or major straits on this leg, the ship stays close to the direct line.

Shipping time depends on speed. At 14 knots, a common container ship service speed, the passage takes 12.8 days at sea. Slow steaming at 12 knots stretches it to 14.9 days, while 18 knots brings it down to 10.0. 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 Gdansk and Charleston to plan the full ocean transit time.

2,674 nm of the route, 62% of it, lies inside North American ECA, North Sea ECA and Baltic 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 Gdansk to Charleston move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Charleston (USCHS) carriers give about 4 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.

Of the 65 port to port routes from Gdansk in this directory, Charleston is the 19th shortest. Closer destinations include Mersin (4,196 nm), Port Said (4,137 nm) and New York (3,814 nm).
