How to Gybe or jibe when sailing

#1. Helmsman: "Get ready to gybe" The crew checks the sheets, secures the new working jib sheet and maintains tension on but uncleats the current working sheet. #2: Crew: "Ready".
#3: Helmsman: "gybing" or "Jibe-Ho" The crew or helmsman begins to center the mainsail. This is very important to prevent an uncontrolled forceful swing of the boom. The helmsman starts to slowly turn the boat as the mainsail is being centered. The boat is turned further and the stern goes through the wind. Once the stern passes through the wind, the mainsail is let out and the jib's leeward sheet is released and the jib is trimmed using the working sheet on the opposite winch.
