When pressure is greater on the port side of the rudder, which direction does the bow go?

When pressure is greater on the port side of the rudder, which direction does the bow go?

• A. Port
• B. Starboard
• C. Bow Up
• D. Bow Down

Answer: (B)

The key idea is that a rudder creates a yawing moment when there is a pressure difference across it. If the pressure on the port side is greater, the force on the rudder is directed toward the starboard. This pushes the stern toward starboard, which rotates the vessel clockwise and makes the bow swing to starboard. The other options describe vertical motion or the opposite turning direction, which aren’t caused by this sideways pressure difference.
