What does it mean to "swamp" a boat?

Swamping a boat refers to the situation when water fills the interior of the vessel, which can occur due to various reasons such as rough weather, taking on water from splashes, or capsizing. When a boat is swamped, it often loses its buoyancy and may become difficult to control or may even sink, which is a significant safety concern. Understanding this term is crucial for boaters to recognize the importance of maintaining their vessels and ensuring that they stay watertight during operations.

The other options do not pertain to the term "swamp" in the context of boating. Repairing, cleaning, and launching a boat are all important activities, but they do not relate to the concept of water entering the boat’s interior.
