Hotel Service Unit 19 Q7 Quiz

Correct Answer:
B) The vertical up-and-down motion of the entire vessel

Explanation:
Heave refers to the entire vessel moving up and down in a vertical motion, typically caused by the combined effect of waves impacting the hull uniformly.

Correct Answer:
B) Large following or head-on waves

Explanation:
Pitch is primarily influenced by waves coming from the front (head seas) or rear (following seas), causing the bow and stern to rise and fall.

Correct Answer:
A) The side-to-side tilting of the vessel

Explanation:
Roll is the side-to-side motion where the vessel tilts alternately to port and starboard, often caused by waves hitting the sides of the ship.

Correct Answer:
B) The forward and backward motion along the vessel’s longitudinal axis

Explanation:
Surge refers to the linear movement forward and backward, typically influenced by acceleration and deceleration forces such as waves or engine thrust.

Correct Answer:
C) Risk of capsizing in extreme cases

Explanation:
Excessive roll can lead to stability issues and, in severe cases, may risk capsizing if the vessel’s center of gravity is compromised.

Correct Answer:
B) Strong head-on waves or sudden changes in speed

Explanation:
Surge can be triggered by waves hitting the vessel from the front or by rapid changes in the vessel’s speed.

Correct Answer:
B) Deviation from the intended course

Explanation:
Yaw can cause the vessel to drift off course, requiring corrections to maintain the desired heading and direction.

Correct Answer:
B) The up-and-down movement of the vessel’s bow and stern

Explanation:
Pitch refers to the longitudinal motion where the vessel moves up and down at the bow and stern, usually due to waves approaching from the front or rear.

Correct Answer:
A) The rotational movement around the vertical axis of the vessel

Explanation:
Yaw is the motion where the vessel rotates around its vertical axis, causing the bow to move side-to-side relative to its intended course.
