What speed defines High speed?

• A. 25 kts or greater
• B. 30 kts or greater
• C. 40 kts or greater
• D. 20 kts or greater

Answer: (B)

The speed threshold defines when a vessel is categorized as high speed. In this context, high-speed craft are those capable of 30 knots or more. Reaching 30 knots marks a switch in performance characteristics, including hull behavior (often planing), wake and spray, maneuverability, and the procedures and safety considerations required for fast operations. That’s why the best answer is 30 knots or greater. Speeds below that don’t meet the defined threshold, while speeds well above it still fall under the same category once the minimum is reached.
