You are proceeding along the right bank of a narrow channel aboard a right- handed single-screw vessel. The vessel starts to sheer due to bank suction/cushion effect. You should __________.

Correct Answer: Option A — increase speed and put the rudder right full

Increasing speed enhances rudder effectiveness, allowing the vessel to overcome the bank suction effect. By applying right full rudder, the vessel uses the increased water flow to steer away from the bank. This is a standard emergency maneuver to correct a sheer caused by hydrodynamic interaction in narrow channels.
