Question 2981 Deck General

The correct answer is C) 75%. According to the regulations governing the manning requirements for towing vessels, 75% of the deck crew must be able to understand any order spoken by the officers. This is to ensure clear communication and safe operations, especially in situations where quick and effective responses are critical. The other options are incorrect because 50% (A) would not provide sufficient redundancy, and 100% (D) would be an overly stringent requirement. 65% (B) is also not the correct percentage specified in the regulations.
