Question 4035 Deck General

The correct answer is C) increase speed and put the rudder right full. When a vessel experiences bank suction/cushion effect, causing it to sheer towards the bank, the appropriate response is to increase speed and put the rudder hard over in the direction of the sheer. This increases the vessel's hydrodynamic forces, counteracting the bank suction and helping the vessel regain control and steer away from the bank. The other options are incorrect because: A) Backing full with rudder amidships would further exacerbate the sheer towards the bank. B) Decreasing speed would reduce the vessel's hydrodynamic forces, making it more susceptible to the bank suction. D) Stopping the engines and putting the rudder left full would be the wrong corrective action, as it would not counteract the rightward sheer.
