That was not the length of the boats but a product of the limiting factors of the rule’s equation. Any of the determining factors such as length, displacement or sail area could be changed but such changes required proportionate change in other factors to compensate. This allowed them to be raced on a level basis. Stability was not taken into account. Limits were set on measurements for waterline length, draft, freeboard and so on.</p><p>The three original surviving Js - Velsheda, Shamrock and Endeavour - have been refitted for worldwide cruising and racing. Their displacements have increased and the yachts no longer rate as a J under the Universal Rule definition, with the exception of Shamrock V, which was the smallest of the Js. </p><p>In total nine J Class yachts are active now with six replicas having been built since 2003; Ranger, Rainbow, Hanuman, Lionheart, Topaz and Svea.</p></div></div></div></div></section><section class="section with-black-bg section-about-association"><div class="container"><div class="padding"><div data-w-id="19b52a3c-2891-c305-d39d-6cf96666ddc4" style="opacity:0"><div class="about-association-title-div"><img src="https://cdn.prod.website-files.com/642edc7ff8ce1469841e617b/64810ba7cc5a19a254333c11_Line%208.svg" loading="lazy" alt=""/><h1 class="about-association-title">The J Class Association</h1><img src="https://cdn.prod.website-files.com/642edc7ff8ce1469841e617b/64810ba7cc5a19a254333c11_Line%208.svg" loading="lazy" alt=""/></div><div class="about-association-rt w-richtext"><p>The J Class Association (JCA) was founded to protect the interests of the Class, present and future.
