What does increased throttle do when compensating for bank cushion?

When compensating for bank cushion, increasing the throttle primarily serves to push the bow away from the bank. Bank cushion occurs when a vessel is navigating close to the shore or bank, and the water pressure against the hull creates buoyancy that can push the vessel toward the bank. By increasing the throttle, the vessel's speed increases, creating more lift and altering the flow of water around the hull. This lift helps to push the bow away from the bank, counteracting the tendency to get pushed towards it.

In situations involving bank cushion, understanding the vessel's behavior in relation to the bank is crucial, as it allows for safer navigation and better handling in tight or narrow channels.
