CHIEF ENGINEER Unit 8 Q2

1 / 8

Why are there different load lines for fresh water and sea water?

A) Fresh water vessels are generally smaller

C) Fresh water is cleaner than sea water

B) Water density differences affect buoyancy, requiring adjustments for safe draft

D) Fresh water is colder than sea water

2 / 8

Which of the following explains why a vessel has a different load line for tropical waters?

C) Tropical waters have fewer currents

B) Tropical waters are generally deeper

A) Tropical waters are warmer, affecting water density

D) Tropical waters are closer to the equator

3 / 8

What is indicated by the “S” line in the load line markings?

C) Special cargo load line

A) Summer load line

D) Structural load limit

B) Starboard side load line

4 / 8

What is the purpose of the Plimsoll mark on a vessel’s load line marking?

B) To show the vessel's maximum load draft in various water conditions

D) To specify the vessel’s year of manufacture

C) To mark the ideal sailing speed

A) To indicate the cargo capacity

5 / 8

Which of the following components are included in a typical load line marking for a vessel certificated to operate in all zones?

A) Summer load line only

C) Load lines for the tropical zone only

D) Only the winter and summer load lines

B) Summer, winter, tropical, and fresh water load lines along with the Plimsoll mark

6 / 8

What is statutory minimum freeboard?

B) The minimum vertical distance between the waterline and the main deck

A) The maximum amount of cargo a ship can carry

D) The distance from the ship's deck to its highest point

C) The space between the hull and cargo hold

7 / 8

If a vessel moves from sea water to fresh water with the same load, how does this affect its draft?

C) The vessel sits lower in fresh water

A) The vessel sits higher in fresh water

B) The vessel’s draft remains the same

D) The vessel moves faster in fresh water

8 / 8

Why is maintaining statutory minimum freeboard important for a vessel?

D) To increase fuel efficiency

A) To ensure faster speed

C) To prevent the deck from submerging under typical load conditions

B) To allow for maximum cargo space
