Nautical Term: Freeing port

Definition of Freeing port

. Freeing port refers to a large opening in the bulwark on an exposed deck of a seagoing vessel. This design allows for the rapid draining of water from the deck, which is essential for maintaining the vessel’s stability and preventing further flooding.

For instance, during a storm at sea, the waves might repeatedly crash against the vessel’s deck, leading to significant flooding. In such a situation, the crew might need to quickly open the freeing ports to allow the water to drain from the deck. This action would help prevent further flooding and maintain the vessel’s stability, allowing the crew to safely navigate the stormy waters.
