A 47-foot boat in 5- to 7-foot seas has an endurance of how many hours?

• A. 12 hours
• B. 6 hours
• C. 4 hours
• D. 8 hours

Answer: (D)

Endurance is the time a boat can operate before it must refuel, based on its fuel capacity and the current fuel burn rate. In heavier seas, the engine works harder and fuel burn increases, often reducing speed and overall efficiency. For a 47-foot boat operating in seas of 5 to 7 feet, the endurance is typically about 8 hours—the value that best matches standard data for that size and sea state. If the seas were calmer, endurance would be longer; in even rougher conditions or with a heavier load, it would be shorter.
