Etymology
the word 'outrigger' is a compound formed from native english elements. its first element, 'out,' derives from old english 'ūt,' meaning "outside." the second element, 'rig,' entered middle english from a scandinavian source, related to old norse 'rigga,' meaning "to bind" or "to fit out a ship." the suffix '-er' denotes an agent. literally, an outrigger is "that which rigs out" or projects outward. the term originally described the projecting spar or framework used to extend a sail on a ship. this sense of a lateral projection was then applied to the stabilizing float attached to the side of a canoe or boat, which is now the primary meaning. the logic of the word perfectly captures its function: a structure that is rigged or fixed to the outside of a vessel.
