Pitch involves rotation about which axis?

• A. The X axis
• B. The Y axis
• C. The Z axis
• D. The diagonal axis

Answer: (B)

Pitch is the rotation around the side-to-side axis, the transverse axis. This axis runs from left to right across the vessel, and rotating about it tilts the bow up or down. In this convention, that side-to-side axis corresponds to the Y axis. So pitch changes the vessel’s vertical angle by lifting or lowering the bow, unlike roll, which is rotation about the fore-aft axis (longitudinal), and yaw, which is rotation about the vertical axis. The diagonal axis isn’t used for these standard motions.
