The International 2.4mR single handed keelboat.

The class is a development class governed by the 2.4mR rule. The class rule is closely related to the 12mR rule that was used in the America's Cup and the shape often resembles the larger sister.


Single handed

The helm sits down inside the boat facing forward with all the controls at arms reach, the sailing is not physically demanding. Also with the ballasted keel to give power the boat is relatively insensitive to crew weight; so old, young, large and small compete on a level playing field when compared to a dinghy class.


Norlin Mk3

While there is a small but active group of amateur designer/builders around the world, around 90% of boats are the commercially produced Norlin Mk3 designed by yacht designer Peter Norlin of Sweden.


Integrated sailing

The 2.4mR is ideal for disabled integrated sailing since the sailor does not move in the boat, and everything is adjustable from right in front of the sailor. Both hand-steering and foot-steering are possible.
