Jury rigging
In maritime transport and sailing, jury rigging or jury-rigging is making temporary makeshift running repairs with only the tools and materials on board. It originates from sail-powered boats and ships. Jury-rigging can be applied to any part of a ship; be it its super-structure (hull, decks), propulsion systems (mast, sails, rigging, engine, transmission, propeller), or controls (helm, rudder, centreboard, daggerboards, rigging).
Similarly, a jury mast is a replacement mast after a dismasting. If necessary, a yard would also be fashioned and stayed to allow a watercraft to resume making way.
The Oxford English Dictionary states that jury-mast is "Of unknown origin", adding "Apparently either a corruption of some earlier name, or a jocular appellation invented by sailors. For the suggestion that it may have been short for injury-mast, no supporting evidence has been found." It defines it as "Nautical: A temporary mast put up in place of one that has been broken or carried away." and the earliest citation given is from 1616, with the spelling lury mast.
The 1881 edition of Brewer's Dictionary of Phrase and Fable defines Jury Mast as "A corruption of joury mast, i.e. a mast for the day, a temporary mast, being a spar used for the nonce when the mast has been carried away. (French, jour, a day)", but the 1970 Centenary Edition of the same work states that "the etymology of 'jury' here is a matter of surmise". A further suggested derivation is from the old French ajurie (aid).
A sail-powered boat may carry a limited amount of repair materials, from which some form of jury-rig can be fashioned. Additionally, anything salvageable, such as a spar or spinnaker pole, could be adapted to carry a makeshift sail.
Ships typically carried a selection of spare parts such as topmasts. However, due to their much larger size, at up to 1 metre (3 ft 3 in) in diameter, the lower masts were too large to carry as spares. Example jury-rig configurations include:
The jury mast knot may provide anchor points for securing makeshift stays and shrouds to support a jury mast, although there is differing evidence of the knot's actual historical use.
Jury-rigs are not limited to sail-powered boats. Any unpowered watercraft can carry jury sail. A rudder, tiller, or any other component can be jury-rigged by improvising a repair out of materials at hand.
