FREE SVOP Vessel Stability and Construction Questions and Answers

Question 1

Which of the following describes the 'free surface effect' on a small vessel?

Accepted Answer

The reduction in stability caused by the movement of liquid in partially filled tanks or compartments.

Answer

The tendency of water on deck to increase buoyancy and stability.

Answer

The increase in speed when a vessel is operating on a calm, flat sea.

Answer

The effect of wind on the exposed surfaces of the hull, causing the vessel to heel.

Question 2

A small vessel has a high Metacentric Height (GM). What handling characteristic is it most likely to exhibit?

Accepted Answer

A quick, stiff, and potentially violent rolling motion.

Answer

A long, slow, and comfortable rolling period.

Answer

A tendency to remain heeled at a significant angle.

Answer

Neutral stability, with little tendency to return upright.

Question 3

You are loading heavy equipment onto your small vessel. To maximize stability and ensure safety, where is the best place to stow this equipment?

Accepted Answer

As low and as close to the vessel's centerline as possible.

Answer

As high as possible on the upper deck to keep it dry.

Answer

On one side of the vessel to balance the weight of the fuel tanks.

Answer

At the extreme bow or stern of the vessel.

Question 4

Which structural component is considered the 'backbone' of a vessel, running along the centerline from bow to stern?

Accepted Answer

Keel

Answer

Bulkhead

Answer

Frame

Answer

Sheer Strake

Question 5

A vessel is described as being 'trimmed by the stern'. What does this mean?

Accepted Answer

The draft at the stern is greater than the draft at the bow.

Answer

The vessel is perfectly level in the water from front to back.

Answer

The draft at the bow is greater than the draft at the stern.

Answer

The vessel is listing to the starboard side.

Question 6

During winter operations, a vessel accumulates a significant amount of ice on its superstructure and rigging. Which of the following is the most dangerous consequence?

Accepted Answer

The ice raises the vessel's center of gravity and reduces stability.

Answer

The ice increases the vessel's overall displacement, making it ride lower.

Answer

The ice makes the deck slippery, creating a hazard for the crew.

Answer

The ice can block scuppers, preventing water from draining off the deck.
