Standing rigging refers to the set of wires and ropes that support a sailboat's mast and keep it in place while sailing. Synonyms for standing rigging include the stay system, the support sail plan, and the fixed sail control system. These terms all describe the essential parts of a sailboat's rigging that keep the mast upright and stable, and they are often used interchangeably. Other synonyms for standing rigging may include the standing lines or the standing gear, which are more general terms that can refer to any stationary ropes or lines used on a sailboat. No matter what it is called, keeping the standing rigging in good condition is essential for safe and efficient sailing.
