What might cause a boat's hull to be damaged when running aground or hitting a submerged object?

• A. Soft mud cushions impact
• B. Water automatically seals cracks
• C. A hard impact with rocks or debris can crack or puncture the hull; inspect for leaks before continuing
• D. The hull expands with speed and becomes stronger

Answer: (C)

Hard impacts with rocks or submerged debris can crack or puncture a boat's hull, creating leaks. When grounding or striking something underwater, that force can compromise the hull’s integrity, so you should inspect for leaks before continuing. A soft mud might cushion the hit but does not guarantee no damage. Water does not automatically seal cracks; any crack or puncture can let water in, so you must assess and repair as needed. The hull does not expand with speed or become stronger; speed can worsen damage rather than improve it.
