What must you remember about exits when trapped in an enclosed cabin during a capsize?

The correct choice indicates that when trapped in an enclosed cabin during a capsize, it is crucial to remember that all exits might be blocked. This highlights the potential danger and unpredictability of a capsized situation, where water can shift the cabin's structure or debris can obstruct pathways. Understanding this helps you prioritize your actions when seeking to escape.

In addition, recognizing that all exits may be blocked underscores the importance of preparation and safety training prior to any boating activity. It prepares crew members to think critically about their environment and encourages them to develop strategies for survival, such as maintaining calmness, assessing the area, and knowing the emergency procedures for such scenarios.

The other options imply varying degrees of accessibility to exits, which can mislead individuals into thinking they have a reliable means of escape. Assuming that some exits may be usable or are irrelevant while submerged could lead to fatal consequences, making it imperative for boat crew members to be aware of the reality that all exits could be compromised during an emergency situation like a capsize.
