The International 2.4mR is a one-person keelboat. The class is a development class governed by the 2.4mR rule. The rule controlled by World Sailing (formerly known as ISAF) is one of the few classes designated as an International class. The 2.4mR class rule is closely related to the 12mR class rule that was used at the America's Cup.

While there is a small but active group of amateur or professional designers and builders around the world, around 90% of the 2.4mR boats are the commercially produced Norlin Mark III designed by Swedish yacht designer Peter Norlin. Over the years, new 2.4mR designs such as the Stradivari III, the Proton and the Super 3 have come into production.

The 2.4mR boats are primarily used for racing and the class holds highly competitive national events in many countries. World and European championships can attract as many as 100 boats each year.

The 2.4mR is ideal for adaptive sailing since the sailor barely moves in the boat, and all settings can be adjusted from a facing forward seated position. Both hand-steering and foot-steering are possible. The boat is sailed without a spinnaker, but it is equipped with a whisker-pole extending outward to hold the shape the jib when sailing downwind. The boat's capability as a truly inclusive sailing boat has been demonstrated over many years at multiple Open World Championships.


After the 1980 America's Cup, people in the Newport, RI area started sailing boats called Mini-12s. They were named after the 12-Metre yachts that were used at the America's Cup. As the fleet started to grow, the word spread to Sweden, home of the yacht designer Peter Norlin. Peter Norlin refined the original designs, and along with other naval architects, they collectively initiated the International 2.4mR class that we know today. Although the 2.4mR is a development class, Peter Norlin has become the dominant designer, and the class is therefore often mistaken as a one-design class.


In recent years attempts have been made to develop a one-design class based on the 2.4 Norlin Mark III. This was primarily because the competition within the Paralympics was meant to be more about the sailors' competitiveness and less about the equipment. This led to the introduction of Appendix K to the Class rules and a group of individuals started to work on a set of stand-alone one-design rules. This is still at the early stages but this effort is likely to lead to the emergence of a new one-design 2.4mR class alongside the existing development 2.4mR class.

Rating formula[edit]

As an open class rather than a one-design, all boat designs must meet the following formula.[3]

(all measurements in mm)

  • L = the "corrected" length of the hull (see rule D.6.3)
  • d = the midship girth difference (see rule D.6.4)
  • F = the average freeboard height (see rule D.6.5)
  • S = the total rated area of the mainsail and jib combined.
