Become a Member, Join the USSCA Class

Whether you’re interested in casual and fun sailing with a great group of helpful, friendly and fun people or want to get faster and better on the water against some of the best champions in the world, the Sunfish Class is the perfect choice for you. Our Mission Statement simply says, “To promote and develop Sunfish Class one-design racing worldwide under uniform rules, enhance the enjoyment of the boat and to provide an efficient medium of exchange of information and friendship among sailors.” That’s a fancy way of saying there’s something for everyone of all ages and genders who want to sail a Sunfish!


     Many local clubs sponsor casual and fun races. But there’s also a world-qualifying racing level if you want to explore your competitiveness. As a recognized International Class by World Sailing, championships are sailed all over the world providing great locations to travel to and combine with a family vacation. The ISCA also works hard to keep membership fees as low as possible and still provide a world class level of sailing from local club sailing to national and world championship sailing.
