Welcome to the ISCA and USSCA Website!

 

ISCA are incredibly popular single-handed sailboats. Raced and cruised in over 20 countries, this flexible, tunable rig makes it suited to a diverse range of sailors. Few classes have women, youth and masters regularly finishing in the top 10 (or winning!) national and World Championships. While new boats are reasonably priced, used boats are plentiful, and with perhaps a new sail you are ready to join the fun!
