Charleston to Montreal shipping route.

Ships leaving Charleston for Montreal head north and cover a sea distance of 2,046 nautical miles (3,790 km), on a direct course. The straight line between the ports is 1,518 km; coastlines and shipping lanes add the rest. No canals on this leg, the extra miles come from sailing around headlands and islands.

At sea, the voyage lasts 7.1 days at 12 knots, 6.1 days at 14 knots and 4.7 days at 18 knots. 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 Montreal to plan the full ocean transit time.

2,033 nm of the route, 99% of it, lies inside North American 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 Montreal move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Montreal (CAMTR) carriers give about 3 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.
