2.4 Metre

After the 1980 America's Cup, people in the Newport, RI area started sailing boats called Mini-12s named for the 12-Metre yachts used in the America's Cup. As the class developed, word of it spread to Sweden, home of yacht designer Peter Norlin. Norlin tweaked the design, and along with other naval architects, he created the 2.4-meter yacht class. Although the 2.4mR is a construction class, Peter Norlin is in practice the totally dominating designer, and the class is therefore often mistaken as a one-design class. In addition to all the sailing aspects of the boat, Norlin has worked the design to incorporate features for the physically disabled to use the boat.

In recent years attempts have been made to develop a one-design class based on the Norlin III. This is primarily because of the need for competition within the Paralympics for racing to be about the sailor and not a technical development race. This led to the introduction of (Appendix K to the Class rules) and now a group is working on a set of stand-alone One-design rules. This is still at the early stages but it is likely a new one-design class is formed alongside the development class.

As an open class rather than a one-design, all boat designs must meet the following formula.[2]

${\displaystyle {\frac {L+2d+{\sqrt {S}}-F}{2.37}}\leq 2.4{\mbox{ metres}}}$

Where (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.
