Some Answers and Explanations

Priority of Way at Sea

1. Which vessel must give way when two power-driven vessels are crossing paths and there is a risk of collision?

  • Correct Answer: A) The vessel which has the other on its starboard side
  • Explanation: According to COLREGs Rule 15, when two power-driven vessels are crossing to involve risk of collision, the vessel which has the other on her starboard side must keep out of the way.

2. In a meeting situation on open water where two sailing vessels are approaching each other, how is the right of way determined?

  • Correct Answer: D) The vessel on a port tack must give way to the vessel on a starboard tack
  • Explanation: The rule of thumb in sailing is that if both vessels have the wind on different sides, the one with the wind on the port side (left) must give way to the one with the wind on the starboard side (right).

3. When a power-driven vessel and a sailing vessel are on a collision course in open water, which statement is true?

  • Correct Answer: B) The power-driven vessel must always give way
  • Explanation: Under the COLREGs, power-driven vessels must give way to sailing vessels under sail alone, emphasizing the vulnerability and limited maneuverability of sailing vessels.

Tides and Currents

4. What causes tides?

  • Correct Answer: B) Gravitational pull of the moon and the sun
  • Explanation: Tides are caused by the combined effects of the gravitational forces exerted by the moon and the sun, and the rotation of the Earth.

5. Which term describes the tide at its highest level?

  • Correct Answer: C) High tide
  • Explanation: High tide is the state at which the tide is at its maximum elevation, resulting from the gravitational pull of the moon and the sun.

6. What is a spring tide?

  • Correct Answer: B) The tide with the greatest difference between high and low water
  • Explanation: Spring tides occur when the sun, moon, and Earth are in alignment (during full moon and new moon), resulting in the highest and lowest tides.

7. When do neap tides occur?

  • Correct Answer: C) During the moon’s first and third quarters
  • Explanation: Neap tides, which have the least difference between high and low water, occur during the moon’s first and third quarters when the sun and moon are at right angles to each other.
