SEAM 5-LEC (LO 3.1) Quiz #3

Why does a ship with greater deadweight have longer stopping distances?

• Wind resistance increases.

• Water resistance decreases.

• The ship becomes less maneuverable.

• More mass requires more force to stop.

How does vessel speed affect the advance and tactical diameter during a turn?

• Increased speed lengthens both the advance and tactical diameter.

• Higher speeds shorten the advance and tactical diameter.

• Speed does not impact the advance or tactical diameter.

• Higher speeds reduce the tactical diameter but do not affect the advance.

Why does ship speed significantly impact stopping distance and turning circle?

• Increased speed reduces water resistance, shortening stopping distance and making the turning circle smaller.

• Higher speed increases momentum, requiring more time and distance to stop and making turns wider.

• Ship speed has no significant impact on stopping distance, but it improves maneuverability in turns.

• Higher speed improves rudder response, allowing the ship to stop faster and turn more sharply.

How is tactical diameter defined for a vessel's maneuvering characteristics?

• The distance traveled perpendicular to the original course after a 90-degree course change.

• The diameter of the circle formed when the ship completes a 360-degree turn.

• The distance traveled perpendicular to the original course when the ship has turned 180 degrees.

• The distance traveled in the original direction from the point where the rudder is applied until the ship has altered its course by 90 degrees.

How is Final diameter defined for a vessel's maneuvering characteristics?

• The distance traveled perpendicular to the original course after a 90-degree course change.

• The diameter of the circle formed when the ship completes a 360-degree turn.

• The distance traveled perpendicular to the original course when the ship has turned 180 degrees.

• The distance traveled in the original direction from the point where the rudder is applied until the ship has altered its course by 90 degrees.

How does an increase in a vessel's draft affect its turning circle?

• A greater draft decreases the turning circle radius, allowing for sharper turns.

• Increased draft enlarges the turning circle, making turns wider and less sharp.

• The draft has no effect on the turning circle.

• A greater draft makes the vessel turn more quickly with a smaller circle.

How does increasing the speed of a vessel affect its turning circle?

• The turning circle becomes smaller, allowing for tighter turns.

• The turning circle remains unchanged regardless of the speed.

• The turning circle becomes larger, requiring more space to complete the turn.

• The vessel’s speed has no effect on the turning circle.

How does insufficient Under-Keel Clearance (UKC) impact the ship's ability to stop in an emergency

• Insufficient UKC allows for faster stopping due to reduced underwater resistance.

• Insufficient UKC increases stopping distance.

• UKC does not impact the ship’s stopping distance in an emergency.

• Greater UKC improves stopping efficiency, allowing the ship to stop more quickly.

How does shallow water typically affect a ship's turning circle compared to deep water?

• Shallow water increases the turning circle, making turns wider.

• Shallow water decreases the turning circle, allowing for sharper turns.

• The turning circle remains unchanged regardless of water depth.

• Shallow water makes the turning circle less predictable but not larger or smaller.

Why is the advance an important factor to consider when planning a vessel's maneuver?

• It determines how quickly the vessel will complete the turn.

• It affects the amount of space required for the vessel to initiate and start the turn.

• It indicates how much sideways movement the vessel will make during the turn.

• It shows how far the vessel will travel in the opposite direction after the turn.
