The position of the wheelover point is based on which of the following factors?

• A. Advance and transfer (based on speed, rudder angle, and turn angle)
• B. Wind direction and current
• C. Ship length and beam
• D. NAVAID bearing and range

Answer: (A)

Wheelover point is defined by how the vessel moves during a turn, described by advance and transfer. Advance is the distance the ship travels along its original course from the moment you put the rudder over until the bow reaches the new course line. Transfer is the lateral distance the ship covers to get from the original track onto the new course line. Both advance and transfer are governed by how fast the ship is moving, how much rudder is applied, and how sharp the turn is (the turn angle). Wind or current can change the actual path, but they don’t determine where the wheelover point lies. Ship length, beam, or NAVAID bearing and range don’t set this geometry either. So the wheelover point is based on advance and transfer, which come from speed, rudder angle, and turn angle.
