How many points of shoring pressure should be applied to doors, hatches, or scuttles?

The correct answer is that the number of points of shoring pressure applied to doors, hatches, or scuttles corresponds directly to the number of dogs or locking mechanisms on the door or hatch. Each dog serves as a secure attachment point that helps distribute the pressure and load evenly, thus enhancing the structural integrity of the door or hatch during damage control operations.

When multiple dogs are present, the application of shoring pressure at each point allows for a more effective seal against water intrusion and strengthens the overall resistance against external forces such as flooding or pressure from the surrounding environment. This method ensures that the door or hatch remains secure under stress, preventing potential failures that could lead to exacerbating damage or compromising safety.

Using one point or two points of pressure without considering the number of dogs would not provide adequate reinforcement, as it may create uneven distribution of force and potentially lead to failure at weak points. Therefore, the number of points of pressure should match the functional locking mechanisms in place to ensure optimal performance.
