The International 420 Dinghy is a sailing dinghy popular for racing and teaching. The hull is fiberglass with internal buoyancy tanks. The 420 has a bermuda rig and 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 or double-handed. The 420 is an International class recognized by World Sailing. The name refers to the boat's length of 420 centimetres (4.2 m; 13 ft 9 in).

History[]

The International 420 was designed by Christian Maury. The class developed rapidly in France, being adopted nationally as a youth trainer for the larger Olympic class International 470. By the late 1960s the class was adopted by a few UK university sailing clubs for training and team racing.

The 420 was designed specifically to be easier to handle than its larger higher-performance cousin, the 470.

Construction[]

The class adopted a policy of "prudent evolution" so as to allow development without making existing dinghies obsolete. The hull's seaworthiness and stability at speed proved to be better than most of its contemporaries, and this together with its modest sail area make it fun to sail in heavy weather and thus an excellent youth trainer, qualities that led to its adoption for that role by the Royal Yachting Association in the mid-1970s.

With its trapeze and spinnaker it provides the capability for advanced sailing techniques for international standard sailors, while still remaining affordable and accessible to beginners. The International 420 maintains a large multinational class association. The combination of effective class management, the boat's inherent sailing qualities, and prudent evolution have contributed to the class's continuing success.

Club 420[]

The Club 420, or C420,^[4] is a derivative of the 420 and is not recognized by World Sailing or the International 420 Class Association. Designed by Vanguard boats in the 1970s, it has a heavier hull, reinforced for durability in institutional sailing, and a stiff, untapered mast. The boat is much more simple to sail, yet lacks the performance of the original dinghy due to its extra weight. The Club 420 is used extensively on the youth race circuit in the US, with over 5,000 boats in North America,^[5] but is not sailed in most other countries. It cannot be used at I420 class events.

Z420[]

The Z420 is a transformation of the Club 420. The Z420 hull is 50 pounds (23 kg) lighter and 40 percent stiffer than the C420. Whereas a C420 hull is composed of six pieces, the Z420 has only three molded components: the hull, the deck, and the mast partners. Unlike the C420, the Z420 does not include a spinnaker or trapeze in its rigging. Z420 boats are specially designed for and were used at the Inter-Collegiate Sailing Association National Championships in 2014 for the first time.^[6]
