Ship Manoeuvring, Handling. Test 9 – Online Maritime Tests

What is the reason for the effect we call squat?

The bow and stern wave make the ship sink lower in the water
Increased velocity and decreased waterpressure around the ship's hull
Decreased velocity and increased water pressure around the ship's hull
Increased effect of gravity due to closeness of the sea-bed

In the shown situation, the bow of your ship is pushed away from the bank. How can you handle this?

Put your engine full astern to stop your ship
Give starboard rudder in order to balance the force of the bank effect and rudder effect
Give hard port rudder to get the ship back in the middle of the channel.
Do nothing as the ship will handle itself
