IPA: /ˈdʒɪbˌbuːm/
KK: /ˈdʒɪbˌbum/
A long pole that extends from the front of a ship, used to support the sail.
The sailor adjusted the jibboom to catch the wind more effectively.
The word 'jibboom' originates from nautical terminology, specifically referring to a spar (a pole) that extends from the bow of a ship to support the jib sail. The term is derived from the combination of 'jib' (a type of sail) and 'boom' (a pole used to extend the sail).
Imagine a pole ('boom') that helps hold out a sail ('jib') on a ship — that's what a jibboom does.
