  1. Question 1

    IMO Resolution A.950 (23) requires coastal states to provide a Maritime Assistance Service. Which one of the given options best describes the reason for this?
    • To monitor a disabled vessel and be a point of contact.
    • To lead a salvage operation on a disabled vessel.
    • To help ship owners get through their legislation.
    • It is a requirement making the VTS operation assist the disabled vessel.

  2. Question 2

    When a tropical storm is in the path of a vessel the best action is to keep going and pass through it. Select the best option that comments on this statement:
    • Statement is incorrect as this could be very dangerous.
    • Statement is correct as there will be no other option if it is on the planned route.
    • Statement is correct as the storm would probably have cleared by the time the vessel got there.
    • Statement is correct as the voyage charter would be breached if the vessel altered course.

  3. Question 3

    Is the following statement true or false? Optimum weather routing avoids bad weather systems altogether:
    • True.
    • False.

  4. Question 4

    Select from the following options the reason why it is important to have adequate reserve stability on a vessel when approaching an area of heavy weather:
    • It is because heavy weather conditions permanently change the initial stability.
    • It is because heavy weather conditions vary the initial stability.
    • It is because IMO regulations require this for heavy weather.
    • It is because strong wind causes large heeling moments.

  5. Question 5

    Select from the given options the best reason why, in heavy weather, greater under keel clearance should be allowed on a passage in coastal waters:
    • Squat values are greater as a vessel maintains higher speed.
    • Vessel motion causes potentially large reductions in clearance values.
    • The vessel's propeller needs more water to have efficient propulsion.
    • As waves pass they reduce the depth of water so the vessel bodily sinks.
