Final quiz 1 1070

Which of the following scenarios necessitates the use of an Immediate Action MOB maneuver?

• A crew member is reported missing during a routine check.

• A passenger is witnessed falling overboard from the bridge.

• A lifebuoy deployed earlier is found without the person.

• The ship receives a distress call about a person in the water nearby.

In an Immediate Action MOB situation, which maneuver is known for bringing the ship back to the casualty's location most quickly?

• Williamson Turn

• Anderson Turn (Single Turn)

• Scharnow Turn

• Boutakov Maneuver

The Williamson Turn, while used in Immediate Action, has what characteristic compared to the Single Turn?

• It takes the ship back to the casualty faster.

• It brings the ship along its original track.

• It involves a tighter turning radius.

• It is more suitable when the casualty is far astern.

When is the Scharnow Turn typically employed in an Immediate Action scenario?

• When the person is very close to the stern.

• When a wider turn is required due to sea conditions.

• When the person is observed to be moving rapidly.

• The text indicates the Scharnow Turn is not appropriate for immediate action.

Which of the following is a primary action taken during a Delayed Action MOB situation?

• Immediately executing a high-speed turn towards the last known position.

• Logging the ship's position and maintaining visual contact if possible.

• Deploying all available rescue craft simultaneously.

• Altering course to the nearest port for assistance.

In a Delayed Action scenario, which MOB maneuver is considered to most surely bring the ship back to the scene of the casualty, especially when the exact time of the incident is uncertain?

• Anderson Turn (Single Turn)

• Scharnow Turn

• Williamson Turn

• A continuous expanding square search pattern.

Why is the Scharnow Turn not considered effective in a Delayed Action situation unless the time elapsed is known?

• It requires a very precise initial course and speed.

• Its turning radius is too large for a delayed response.

• Accurately determining the commencement point of the maneuver is difficult without knowing the time of the fall.

• It is only suitable for high-speed vessels.

What is the initial critical step when a Person Missing Action is initiated?

• Immediately commence a Williamson Turn.

• Alerting all crew and activating the MOB alarm.

• Contacting nearby vessels for assistance.

• Reducing ship speed to facilitate a visual search from the bridge.

After raising the alarm in a Person Missing Action, what is the subsequent crucial step before initiating broader search patterns?

• Deploying lifebuoys with smoke and light signals.

• Conducting a systematic search of the ship.

• Calculating the estimated drift of the person overboard.

• Preparing the rescue boat for immediate launch.

The primary goal of any MOB maneuver is to:

• Maintain the ship's schedule with minimal disruption.

• Practice emergency procedures for crew training.

• Recover the person overboard as quickly and safely as possible.

• Avoid collision with other vessels in the vicinity.
