When the ship is empty it rides very high in the water, bobbing around like a cork. This is unstable and uncomfortable for the crew.

The US used a convoy system where a group of ships was shepherded across the Atlantic under the protection of war-ships .

This system was commonly used during World War I and World War II to safeguard merchant ships from submarines and other threats.
