Sample 3

The product of a force times a distance is referred to as:

• Heel

• List

• Moment

• None of the above

A vessel’s inclination to one side due to internal forces such as an unequal distribution of weights is defined as

• Trim

• Heel

• List

• Draft

A vessel proceeds from fresh water to salt water. What will happen to the vessel’s draft?

• The vessel will trim by the head and increase her draft

• The vessel will trim by the stern and the draft will increase

• There will be no change in the vessel’s trim, but the draft will decrease

• There will be no change in the vessel’s trim, but the draft will increase

What would the ship’s stability condition be if the center of gravity coincided with the metacenter?

• The ship would have excessive stability

• The ship would be in a condition of neutral equilibrium

• The ship would have a positive GM

• The ship would have a negative GM

What dangers are involved in overloading?

• A reduction of freeboard and adverse effect of this on stability

• There is greater possibility of structural damage by shipping heavy seas

• Injury to crew members by the heavy seas

• None of the above

What is the danger of having a tank only partially filled?

• The position of the metacenter moves creating an upsetting lever

• G moves vertically upward causing adverse effects on the vessel’s stability

• When the ship heels, the surface of the liquid remains parallel to the waterline

• There is no danger

How is the center of gravity affected if a weight is loaded, removed or shifted on a vessel?

• The center of gravity moves towards a weight removed

• The center of gravity moves away from a weight loaded

• When a weight is shifted within the vessel, the center of gravity is not affected

• The center of gravity moves in the same direction as, and parallel to weight added or shifted

What is the danger of excessive trim?

• The vessel’s bow would ride higher in the water and helm control would be lost

• The vessel would “plane” and cause structural damage

  c. It can affect the transverse stability and the GZ could be jeopardized

• It can affect the transverse stability and the GZ could be jeopardized

• The steering gear compartment could become flooded and the autopilot may not work properly

The safe functioning of a roll-dampening paravane system is largely dependent on:

• The towing speed and on their complementary operation

• The size of the equipment

• The type of vessel

• All of the above

You are lifting a set of fish with the ship’s boom. Where will the weight act?

• At the lowest part of the net

• At the center of the net

• At the side of the vessel where the weight is hosted

• At the point of suspension
