Everything you need to know about the class and the boat

The Class

Every 2.4 must follow the Class Rules. This covers all elements, including specifications, materials, and required tools.

The International 2.4mR Class Association is the global body that regulates the International 2.4mR Class (2.4mR) and the 2.4 Norlin One Design Class (2.4 NOD).

Both 2.4mR and 2.4 NOD vessels comply with the 2.4mR Rating Rule.

The 2.4mR World Championship encompasses all 2.4mR boats, with the inaugural boat receiving the World Cup Trophy and the first 2.4 NOD boat being awarded the 2.4 NOD Trophy.

The International 2.4mR Class Association (ICA)

The International 2.4mR Class Association (ICA) is the governing body for the 2.4 Metre sailboat class, a development class that was granted international status by World Sailing in 1993 and is administered by Member National Authorities around the world. The ICA oversees boat certification, class rules, measurement standards, and buoyancy requirements to ensure all 2.4mR boats are eligible for racing. The organization also manages the 2.4 Norlin One Design (NOD) subclass, supports National Class Associations (NCAs) with funding and promotional activities, and coordinates international championships and events.

The U.S. 2.4mR Class Association

The US 2.4mR Class Association operates as a National Class Association (NCA) under the authority granted by the International 2.4mR Class Association (ICA), which is the global governing body that sets class rules, administers boat certification, and coordinates international championships. The ICA delegates administrative functions to Member National Authorities and NCAs like the US association, which serve as the Certification Authority for their respective countries and handle local boat registration, measurement certification, and member services. The US NCA is responsible for promoting the class domestically, sanctioning national events and championships, maintaining member rosters, and ensuring compliance with ICA class rules while reporting membership activities and election results back to the international organization.

FAQ

What is the 2.4mR?

The 2.4mR is a one-person keelboat that offers even the most accomplished competitive sailors a unique opportunity to test their sailing skills. As complex and challenging as an Etchells or a Dragon without the high maintenance costs or the need for crew, it can be used as a platform to further develop team and fleet racing.

Why is the 2.4 sometimes called "the great equalizer"?

All controls are positioned in front of the helmsperson, making each trim control readily accessible. A sailor can steer using either their hands or feet. The sailor's weight is near the center of gravity; hence, the size and fitness level of the sailor have minimal impact on speed. In other words, the 2.4mR is considered the most inclusive sailing boat currently available, allowing all competitors to be virtually equal on the water, regardless of their age, physical strength, or gender. The high demands on each individual stem entirely from pure sailing skills, focusing on strategy, sail trim, and speed.

When are the races scheduled?

Races are held weekly from May through September, Sunday mornings (weather dependent).

How do I maintain my boat?

Regular cleaning and checking rigging keeps your 2.4 race-ready. Fleet wide we have a lot of experience in fiberglass repair, hardware upgrades, line splicing and problem solving. All you have to do is ask and someone will have that "skill" you need.

How do I transport a 2.4?

There are several options for moving your 2.4 over land. Open trailer, enclosed trailer and even in the bed of a pick-up truck. As a Fleet, we have several options available. Sometimes it's as easy as sharing a trailer.

How much does a 2.4 cost?

As you may be aware, a boat is essentially a hole in the water where you throw your money, and a 2.4 is no exception, other than being a smaller hole. With any boat, the value comes from the manufacture, how it was maintained, damage history and age (although not a factor for well maintained boats).

Bottom line, a used 2.4 can range from $1000 to $15,000. Sails will set you back between $1400 and $1800 (depending on manufacturer and type). If you replace every line on the boat you can expect $200 to $400. Don't forget your personal gear (foul weather gear, splash top, dry suit, life jacket, electronics) add up quick. If you are just getting stared, a used boat with used sails is just fine. Its about getting out there.
