What is the purpose of a capacity plate on a boat?

• A. To show the maximum safe load and number of people the boat can carry, aiding stability.
• B. To indicate the boat's speed rating.
• C. To display the keel depth for anchor use.
• D. To identify the hull color and finish.

Answer: (A)

The capacity plate tells you the maximum safe load and the number of people the boat can carry, which is essential for keeping the vessel stable and afloat. This rating comes from the boat’s design, flotation, and balance, and following it helps ensure the weight is distributed so the hull maintains its righting moment and buoyancy.

Staying within the plate’s limits prevents overloading, which can raise the center of gravity, reduce stability, and make handling, steering, and stopping more difficult. It also helps protect fuel, gear, and passengers from being carried in a way that could lead to capsizing or swamping in rough conditions or during quick maneuvers.

The capacity plate is usually placed where it’s easy to see before launch and is specifically about load and people. It does not indicate speed rating, keel depth for anchor use, or hull color and finish.
