In ship maneuvering, which term describes the distance the vessel moves along its original course from the moment the rudder is put over until the new course is established?

• A. Lateral Shift
• B. Pivot
• C. Drift
• D. Advance

Answer: (D)

When a vessel starts turning, its path is a curved arc. The distance it travels forward along its original course from the moment you put the rudder over until the heading actually aligns with the new course is called the advance. It’s a measure of how much forward progress happens before the ship settles on the new track. This concept is useful alongside other turn metrics to understand turning performance. The other terms describe different aspects: lateral shift is the sideways departure from the original line, drift is the sideways movement caused by current or wind, and pivot refers to turning about a fixed point rather than the forward distance along the original course.
