Which option best describes the wheelover calculation factors?

• A. Advance and transfer
• B. Course over ground and wind drift
• C. Turn rate relative to heading
• D. Advance and transfer (based on speed, rudder angle, and turn angle)

Answer: (D)

Wheelover planning relies on how the vessel actually moves when it starts a turn. The two distances you must understand are advance—the distance traveled along the initial course before the turning arc brings you onto the new course—and transfer—the distance traveled during the turn until you intersect that new course. These distances aren’t fixed; they depend on how fast you’re going, how far you deflect the rudder (which sets the turn rate), and how large a change in direction you’re aiming for (the turn angle). So describing wheelover in terms of advance and transfer and noting that they’re based on speed, rudder angle, and turn angle captures the core calculation you perform to place the vessel on the new course. The other options touch on related ideas like wind drift or turn rate, but they don’t specify the essential wheelover distances or the exact inputs that determine them.
