Understanding Ocean Currents and Squat

What is a primary factor causing ocean currents?

• Earth's rotation

• Ship speed

• Fuel consumption

• Cargo weight

What happens when a current is from the stern?

• Increased maneuverability

• Decreased speed over ground

• Reduced maneuverability

• Shorter stopping distance

Which of the following is an effect of a current from ahead?

• Harder to hold position

• Improved maneuverability

• Increased speed over ground

• Reduced stopping power

What happens when a transverse current affects a ship?

• No impact on course

• Increased ability to hold position

• Lateral drift

• Faster steering response

What is the primary cause of squat?

• Wind resistance

• Water displacement due to ship movement

• Fuel combustion

• Cargo weight distribution

When does squat occur?

• Only in deep water

• Only when stationary

• When a ship moves through water or is in a flowing current

• Only during docking

What is a key indicator that squat is occurring?

• Increased speed

• No change in ship response

• Appreciable hull vibrations

• Reduced fuel consumption

How does squat affect a ship’s maneuverability?

• It improves response time

• It makes maneuvering more difficult

• It reduces drag

• It increases engine efficiency

What factor most significantly influences the degree of squat?

• Ship’s weight

• Ship’s speed

• Cargo type

• Wind direction

What happens to water flow under the hull in shallow waters?

• It slows down

• It increases in velocity

• It stops completely

• It flows in reverse
