A lifeboat is afloat alongside after a drill. Both lifting rings are attached and the falls are slack. The forward hook indicates fully reset, but the aft hook does not. Before the winch operator takes the boat's weight, what must be done?
Correct answer: C - Reset and verify the aft hook while the boat remains supported by the water.
Several occupants of an enclosed motor lifeboat develop headache, dizziness, and nausea soon after the engine starts. Seas remain slight. Those sitting nearest the engine enclosure become affected first, and one is now confused. Which condition best explains the pattern?
Correct answer: D - Carbon monoxide exposure
An abandon-ship order has been given when the vessel loses electrical power. Its lifeboat uses gravity davits, an electric hoisting motor, and a mechanically controlled lowering brake. The installation is undamaged and the launch path is clear. How does the blackout affect launching?
Correct answer: C - Gravity can still lower the boat; the mechanical brake controls the descent.
A motor lifeboat is swinging to starboard when the coxswain orders, 'Midships.' What action does that order require from the helmsman?
Correct answer: A - Center the rudder; the boat may continue swinging after it is centered.
Sunlight is strong, and a search aircraft is still several miles from the lifeboat. Which device allows repeated attempts to attract the pilot's attention without expending pyrotechnics?
Correct answer: C - A signal mirror aimed toward the aircraft
As a vessel sinks, its liferaft container floats free, the painter pays out, and the raft inflates. The vessel continues downward. Which part of the float-free arrangement is intended to let the inflated raft separate before it is dragged under?
Correct answer: D - The weak link in the painter attachment
A half-submerged cargo container is drifting through a busy approach channel at dusk. No vessel is presently in distress, but approaching traffic needs a warning. The rescue boat's radiotelephone broadcast should use:
Correct answer: A - SECURITE (safety)
A search vessel reports twelve regularly spaced dots extending outward along a single bearing on its X-band radar. The innermost dot is about 3 nautical miles away. For the crew trying to locate the survivors, how should that display be interpreted?
Correct answer: A - A radar SART is near the innermost dot, about 3 nautical miles away.
The equipment inventory for a SOLAS A liferaft approved for 25 persons lists two thermal protective aids. Only 16 people are assigned to that raft. What correction is needed to meet the LSA Code's minimum quantity?
Correct answer: B - Add one aid; the 25-person capacity requires three.
A child's weight is within the range marked on an approved foam-filled lifejacket. Even with its straps adjusted as instructed, lifting gently at the shoulders brings the jacket up over the child's chin and ears. Which conclusion should govern its use?
Correct answer: C - The fit is insecure; select another suitable approved size or model.
