Goosewinging (or "wing and wing") is a sailing maneuver used when running directly downwind. It involves setting the main sail on one side of the boat and the headsail (jib or genoa) on the opposite side to maximize sail area. A whisker pole is often used to hold the headsail out.

Key Details of Goosewinging:
Purpose: Maximizes downwind speed and stability, preventing the jib from being covered by the mainsail.

Usage: Commonly used in light to moderate winds when sailing in the same direction as the wind.

Risk: Requires careful steering to prevent an accidental gybe of the main sail.

Alternative Definition: In traditional sailing, it refers to hauling up the middle part of a square sail and allowing only the weather clew (corner) to catch the wind.

Often, sailors refer to this as sailing "wing on wing" or "wing and wing," especially with cruising sailboats using a spinnaker pole or whisker pole to hold the headsail opposite the boom.
