The Club 420 Class is a double-handed (2 crew) monohull planing dinghy with centerboard, 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 spinnaker and optional trapeze, making teamwork necessary to sail it well.
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 420 was designed specifically to be easier to handle than its larger higher-performance cousin, the 470. The boats are very similar in appearance than International 420 but the club 420 is slightly stronger, heavier and less refined. A key difference is the decreased flexibility of the mast in the Club 420.
Originally created by the Harken Brothers (Vanguard Boats) in the US they acquired a license to build the International 420 however they ended up producing the Club 420.The Club 420 forms the base of many local, high school and collegiate programs in North America.
Simple and safe for beginning sailors and yet challenging enough for collegiate champions, the C420 offers more learning opportunities than any other double-handed boat in North America. Over 7,000 Club 420s are sailed in youth programs all over the United States, Canada and the Caribbean.
