Hey Guys,
Several boat copanies think they have copied the self tacking jib system. This is not so. I have not seen a so called "self tacking jib system" on any boat except an ARC product that works properly. The copy cats have extra lines and cleats to control this and that and are much more complicated than the ARC system and they do not work as well. If you are going to add a self tacking jib system to your boat, check out an ARC product carefully and you will see that there are many subtle points that make this system simplier and more automatic than the copy cats.
