Usually, the berthing angles not equal to the approaching angle. The approaching angle should be altered to the berthing angle prior to the ship's lateral moving to the wharf. Altering the approaching angle, when there is a wide angle between the berth and the channel or fairway, is the process equivalent to a large angle of heading altering. The approaching angle is correlated to the area of touch at the time a ship contacts her berth. If the berthing angle not zero degree, the area of first touch maybe small, the hull of the ship may touch only one fender furnished at the wharf and may damage the structure of berth and/or the hull of herself if her transverse speed is a bit fast. Ship's heading should be parallel to the wharf at the moment she contacts whatever the way is employed to move the ship close to her berth.Usually, the larger is the displacement, the smaller is the angle of close to be employed. The stronger is the current a full loaded ship is moving against, the smaller is the angle. The stronger is the off shore wind, the larger is the angle for a light loaded ship. A ship of small size can employ a small berthing angle and of medium or large size must employ zero berthing angle to move laterally with her ship's heading kept parallel to the wharf as her huge inertia difficult to be controlled.The berthing angle is the angle between ____ and ____.A channel; berthB heading; berthC heading; channelD course; channel

The berthing angle is the angle between heading and shoreline of the wharf. Usually, the berthing angles not equal to the approaching angle.
