Question 2085Deck Safety70% to pass
Reducing the liquid free surfaces in a vessel reduces the _______________.
AI Explanation
The correct answer is B) roll period.
Reducing the liquid free surfaces in a vessel reduces the vessel's roll period, which is the time it takes for the vessel to complete one full roll from one side to the other and back. This is because the reduction in free surface area decreases the vessel's ability to roll, resulting in a shorter roll period.
The other options are incorrect because:
A) Reducing free surfaces does not directly affect the metacentric height, which is a measure of a vessel's stability.
C) Reducing free surfaces does not affect the vessel's draft, which is the depth of the vessel in the water.
D) Reducing free surfaces does not affect the waterplane area, which is the area of the vessel's hull in contact with the water.
