When moving from deep water into shallow water, what risk can arise if speed decreases?

• A. Grounding
• B. Capsizing
• C. Hull breach
• D. Propeller cavitation

Answer: (A)

When you move into shallow water, the available depth becomes the limiting factor for your hull. If the vessel slows down, it relies more on buoyancy and settles deeper in the water, increasing the draft relative to the shallow depth. That extra submersion brings the hull closer to or into contact with the bottom, creating a grounding risk. The other issues listed aren’t directly caused by slowing in this shallow transition: capsizing is about instability, hull breach is a structural failure, and cavitation is a high-speed propulsion problem not specifically tied to this depth-change scenario. Grounding is the most direct consequence of reduced speed in shallow water.
