Hotel Service Unit 16 Q3 Quiz

Correct Answer:
B) Stabilizing tanks generally require less maintenance as they are passive systems

Explanation:
Since stabilizing tanks lack the complex moving parts of fin stabilizers, they tend to require less maintenance, making them a low-maintenance option for roll reduction.

Correct Answer:
A) It is effective at all vessel speeds, including low and stationary speeds

Explanation:
Stabilizing tank systems work based on the movement of water within the tank and can be effective even at low or stationary speeds, unlike fin stabilizers, which are less effective when the vessel is stationary or moving slowly.

Correct Answer:
C) Free surface anti-roll tanks

Explanation:
Free surface anti-roll tanks are designed to use the movement of water within the tank to counteract rolling motion, providing stability to the vessel.

Correct Answer:
B) It reduces the vessel’s fuel efficiency

Explanation:
Stabilizing tank systems add weight and increase resistance due to the water movement within the tank, potentially reducing the vessel’s fuel efficiency compared to fin stabilizers.

Correct Answer:
C) Fin stabilizers are generally more efficient at higher speeds

Explanation:
Fin stabilizers are most effective at higher speeds, as they generate lift through water flow, making them a preferred choice for vessels that operate mainly at cruising speeds.

Correct Answer:
C) U-tube anti-roll tanks

Explanation:
U-tube anti-roll tanks consist of two tanks connected by a channel, allowing water to flow in response to rolling, creating a counteracting force to reduce roll.

Correct Answer:
C) They are less effective at low speeds and increase drag at high speeds

Explanation:
Fin stabilizers rely on water flow for effectiveness and are less efficient at low speeds. Additionally, they create drag, which can impact fuel efficiency at higher speeds.
