In patching a hull breach at sea, what is the first step?

• A. Stop the water flow into the hole.
• B. Inspect for hidden leaks.
• C. Position a canvas patch before inspecting the hole.
• D. Notify the bridge crew and stand by for instructions.

Answer: (A)

The first step is to stop the water flow into the hole. Controlling the flooding immediately reduces the rate at which the hull takes on water, helps maintain buoyancy and stability, and buys crucial time to plan and apply a proper patch. Once the inflow is halted, you can safely inspect the hole for its size and shape, look for hidden leaks, and decide the best patching method. Patching before stopping the flow can let water keep coming in and obscure the hole’s true dimensions, making the repair more difficult. Notifying the bridge crew is important, but it should come after you have first stabilized the flooding.
