Question 1962 Deck Safety

The correct answer is A) device to force a water tight door against the frame. In nautical terminology, a "dog" refers to a device used to secure a watertight door or hatch against its frame. This device is designed to create a tight seal and prevent water from entering the vessel. The dog, typically made of metal, is used to lock the door or hatch in place, ensuring the integrity of the watertight compartment. The other options (B, C, and D) are not the correct nautical definition of a "dog." A crowbar, heavy steel beam, and wedge are not the specific devices used to secure watertight doors on ships and boats.
