In maritime transport and sailing, jury rigging[1] 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.[2] If necessary, a yard would also be fashioned and stayed to allow a watercraft to resume making way.
