Jury rigging (also called "jerry rigging" and by similar phrases) is both a noun and a verb describing makeshift repairs made with only the tools and materials at hand. Its origin lies in such efforts done on boats and ships, characteristically sail powered to begin with. After a dismasting, a replacement mast, often referred to as a jury mast, and if necessary yard would be fashioned and stayed to allow a craft to resume making way.
