The J/24 is no longer considered the most modern sailboat in its class, but it is still a very popular sailboat among keel boat racers. While some of the world's best J/24 sailors have the latest version J/24, a well-prepared 1977 model, built to the same shape and weight with rigid end-grained balsa core construction can still win sailing the class world championship even after 30,000+ miles of trailering. This is one of the many advantages of One-Design sailing that the J/24 is benefitting from. Another reason for its popularity is that it is fairly easy and inexpensive to get hold of a used boat due to the number of boats produced. There are 136 active fleets in the US alone, which offer a lot of race competition. This makes the J/24 a popular boat for beginners and experienced sailors.
