Breeches buoy

A breeches buoy is a crude rope-based rescue device used to extract people from wrecked vessels, or to transfer people from one location to another in situations of danger. The device resembles a round emergency personal flotation device with a leg harness attached. It is similar to a zip line.The breeches buoy was usually deployed from either ship to ship, or ship to shore using a rocket, kite system, or a lyle gun, and allowed single person evacuations. A line is attached to the ship, and the person being rescued is pulled to shore in the breeches buoy which rides the line similar to a zip line.
