What does "capsizing" mean?

Capsizing refers specifically to a situation in which a vessel overturns in the water, causing it to become inverted or flipped over. This can occur due to various factors, including unstable loading, excessive speed, or rough sea conditions. Understanding the risk of capsizing is crucial for ensuring safe boating practices, as it can lead to dangerous situations for all on board.

In this context, the other options do not accurately describe capsizing. A vessel moving quickly does not imply any instability or overturning. Docking and anchoring both involve a vessel being secured in place but do not involve any risk of losing stability or tipping into the water. Therefore, the correct definition of capsizing is that it is when a vessel overturns in the water.
