420 One Design
The International 420 Dinghy is a two crew monohull planing dinghy with centreboard, bermuda rig and center sheeting. The name describes the overall length of the boat in centimeters (the boat is exactly 4.2 meters long). The hull is fiberglass with internal buoyancy tanks. The 420 is equipped with an optional spinnaker and trapeze. It has a large sail-area-to-weight ratio, and is designed to plane easily. It can be rigged to be sailed single-handed. The Club 420 is a derivative of the International 420 dinghy. This class is not recognized by World Sailing or the International 420 Class Association and cannot be used at I420 class events.
