About This Quiz

Have you ever been on the deck of a large vessel, such as a ship? Do you think you can pass this quiz? With this quiz, you will be expected to know what and how long a fathom is, what indicates reserve buoyancy, what should be released when launching a lifeboat, and how many feet is a shot of chain?

If the vertical center of gravity(VCG) of a ship rises, the
- righting arm (GZ) for the verious angles of inclination will decrease
- righting arm (GZ) for the verious angles of inclination will increase
- righting arm (GZ) for the verious angles of inclination will remain unchanged
Correct Answer

A. righting arm (GZ) for the verious angles of inclination will decrease

Explanation

The righting arm (GZ) is a measure of the stability of a ship, and it represents the distance between the center of gravity (CG) and the metacenter (M) of the ship. When the vertical center of gravity (VCG) of a ship rises, it means that the CG moves higher above the waterline. This results in a decrease in the distance between the CG and the metacenter, leading to a decrease in the righting arm (GZ) for various angles of inclination. As a result, the ship becomes less stable and more prone to capsizing.

What action will affect the trim of a vessel?
- All of the above
- Moving high weights lower
- Adding weight at the center
- Moving a weight forward
Correct Answer

A. All of the above

Explanation

All of the actions mentioned in the answer will affect the trim of a vessel. Moving high weights lower will lower the center of gravity, which can affect the trim. Adding weight at the center will also change the distribution of weight and impact the trim. Similarly, moving a weight forward will shift the balance of the vessel and affect the trim. Therefore, all of these actions can have an impact on the trim of a vessel.

The marking on an anchor chain for 30 fathoms is
- Two links on each side of the 30 fathom detachable link, painted white
- One link on each side of the 30 fathom detachable link, painted white
Correct Answer

A. Two links on each side of the 30 fathom detachable link, painted white

Explanation

a shot of chain is indicated every 15 fathoms, by a DETACHABLE LINK PAINTED RED, WHITE, BLUE, then repeats RED WHITE BLUE, until the next to last shot which is YELLOW!, then the ENTIRE FINAL SHOT IS PAINTED RED!!!

red, white, blue, red, yellow until end, then red at last 15 fathoms.

The markings at 15 fathoms indicate one shot.

also 1 link on either side is painted for the first SHOT(15 fathoms), 2 links are painted on each side of the detachable link for the second shot(30 fathoms), 3 links painted for the third SHOT (45 fathoms), and so on, 4 links for the 4th, 5 for the 5th shot

What is true of a tender vessel?
- Long period of roll
- Low center of gravity
- It has a large GM
Correct Answer

A. Long period of roll

Explanation

A tender vessel refers to a ship or boat that has a tendency to roll or sway excessively in response to waves or other external forces. This means that it has a long period of roll, which indicates that it takes a longer time for the vessel to complete one full roll motion. This can make the vessel more unstable and prone to rolling, especially in rough seas. The other options, low center of gravity and large GM, are not necessarily true of all tender vessels and can vary depending on the specific design and characteristics of the vessel.

What is classified as a B-II fire extinguisher?
- 2 1/2 gallon foam
- 20 pound dry chemical
- 2-1/2 gallon soda acid
- 1-1/4 gallon foam
Correct Answer

A. 2 1/2 gallon foam

Explanation

A B-II fire extinguisher is classified as a 2 1/2 gallon foam extinguisher. This type of extinguisher is specifically designed to combat fires caused by flammable liquids such as gasoline, oil, and solvents. The foam agent in the extinguisher helps to smother the fire and prevent re-ignition. The 2 1/2 gallon size refers to the capacity of the extinguisher, indicating that it can hold a larger amount of foam agent compared to smaller extinguishers. This makes it suitable for larger fires or areas that require a higher volume of extinguishing agent.

A crack in the deck plating of a vessel may be temporarily prevented from increasing in length by:
- Drilling a hole at each end of the crack
- Welding a doubler over the crack
- Cutting an oval notch at each end of the crack
Correct Answer

A. Drilling a hole at each end of the crack

Explanation

Drilling a hole at each end of the crack can temporarily prevent it from increasing in length because it relieves the stress concentration at the crack tip. By drilling holes, the stress is distributed more evenly, reducing the likelihood of the crack propagating further. This technique is commonly used as a temporary measure to prevent crack growth until a permanent repair can be made.
