Cargo ships generally travel at speeds ranging from about 12 to 25 knots (approximately 14 to 29 miles per hour). The exact speed depends on the type and size of the ship, as well as operational considerations like fuel efficiency and weather conditions.
- Typical speeds for container ships are around 17 to 24 knots, with some larger bulk carriers traveling slower, around 12 to 15 knots
- The average cargo ship speed is often about 14 to 16 knots (16 to 18 mph), although some container ships can reach up to 24 knots (28 mph)
- The fastest cargo ships, such as certain Panamax container ships like the Maersk Boston, can reach speeds up to about 35-37 knots (40-43 mph), but these are exceptions rather than the norm
- Many ships operate at slower speeds, a practice called "slow steaming," to save fuel and reduce emissions, typically cruising at 18 to 20 knots instead of their maximum speed
In summary, while cargo ships can technically reach speeds over 30 knots, most operate between 12 and 24 knots, balancing speed with fuel economy and environmental concerns.
