What is one indication of flooding in an area?

The presence of condensation on doors or bulkheads, as well as water on the deck, is a clear indication of flooding in an area. This is because flooding typically results in excess moisture and can lead to water accumulating in places where it normally shouldn't be. Condensation occurs when warm, moist air comes into contact with cooler surfaces, leading to the buildup of moisture. When water is actually pooling on the deck, it is a direct sign that there is a breach in the vessel's integrity, or that water is entering the space where it shouldn't be.

In contrast, while unusual noises and strong odors can be indicators of various problems on a vessel, they are not direct or definitive signs of flooding. Smoke on the water may suggest a fire incident or some form of environmental pollution, but it does not specifically indicate flooding. Thus, the observation of condensation or water accumulation provides a more reliable confirmation of flooding.
