Used on small dinghys and skiffs to help keep the boat balanced. The trapeze consists of a wire with one end attached to the mast fairly high up and long enough to reach the deck. The bottom end of the wire has a ring on it. One of the crew members wears a harness with a hook on it. When sailing they hook into the ring on the wire and stand off the side of the boat, hanging horizontal like a giant lever, their feet on the rail and their body perpendicular to the hull. Examples of boats with a trapeze are 470s, 49ers, and One Design 14s.
