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 C — increase speed and put the rudder right full

When experiencing a bank sheer, increasing engine speed enhances water flow past the rudder to regain steering control, while applying hard opposite rudder drives the stern away from the bank, countering the suction and cushion moments pulling the vessel off track.
