What should be done if a boat gains water?

When a boat begins to take on water, the priority is to manage the situation effectively to ensure safety. Using a bilge pump to remove the water is the most immediate and practical response to address the problem. A bilge pump is specifically designed to pump excess water out of the boat, helping to stabilize the vessel and prevent it from becoming swamped or capsized. This action directly targets the source of the issue—excess water—thus providing a proactive measure to maintain the boat's buoyancy and stability.

Other responses, while potentially relevant in specific contexts, do not directly alleviate the immediate problem of water accumulation. Turning off the engine may be appropriate in certain scenarios to prevent damage but does not address the water issue. Calling for assistance could be necessary if the situation worsens, but it does not provide an immediate remedy. Continuing to the nearest dock without addressing the water could lead to a dangerous situation if the boat continues to take on water, potentially risking the lives of those onboard. Therefore, the most effective and responsible action is to use a bilge pump to remove the water directly.
