What is the minimum height for the official number displayed on the interior hull?

• A. 3 inches.
• B. 1 inch.
• C. 4 inches.
• D. 2 inches.

Answer: (A)

The main idea here is legibility of the vessel’s official number. The registration number must be large enough to be read clearly, even on smaller craft or from a short distance. For the interior hull, the minimum height that guarantees readability is three inches. A smaller size, like one or two inches, would not meet the standard, while four inches would still be acceptable but is not the minimum. This requirement helps authorities identify the boat during inspections or in incidents, ensuring proper registration is visible and legible.
