The steering device located on the stern of the boat is the?

• A. Propeller
• B. Rudder
• C. Helm
• D. Hatch

Answer: (B)

The key idea is how steering is achieved on a boat. The part that actually changes the boat’s direction when you steer is the rudder—a hinged blade mounted at or near the stern. When you move the helm, the rudder deflects the water flow beneath the hull, creating a sideways force that turns the boat. The propeller provides thrust to push the boat but doesn’t steer by itself. The helm is the steering control you operate (the wheel or tiller) to move the rudder, and the hatch is just an access cover with no steering role. So, the steering device located on the stern is the rudder.
