Question 374General Subjects - 1st Asst/Chief

The correct answer is B) 3000 kW/4000 HP. According to the Code of Federal Regulations (CFR) Title 46, Section 15.705, all vessels of 3,000 kW (4,000 HP) or more propulsion power are required to have an officer in charge of the engineering watch at all times while in port. This regulation ensures that a qualified engineer is continuously monitoring and maintaining the ship's propulsion and auxiliary systems to maintain safety and readiness. The other options are incorrect because the power thresholds are either too low (750 kW/1000 HP) or too high (6,000 kW/8,000 HP and 7,500 kW/10,000 HP) compared to the regulatory requirement of 3,000 kW/4,000 HP.
