A jib is a type of sail used on a sailing vessel, typically located at the front of the boat. It is triangular in shape and helps to catch the wind, allowing the boat to move forward. Jibs are often used in combination with other sails, such as the mainsail, to improve the vessel's performance and maneuverability. In addition to sailing, the term "jib" can also refer to a type of crane used in construction. This crane has a horizontal arm that extends out from a vertical mast, allowing it to lift and move heavy materials. Both uses of the term highlight the importance of jibs in their respective fields.
