The Wayfarer-world is subject to the same class rules as are all the other types. For racing its self-bailers must also be equal to or smaller than the Andersen/Elvsrom Supermax. You may have guessed it altready, the Supermax is also the standard self-bailer for the Wayfarer-world.
Ah I see, in that case, my old boat had smaller bailers (but the same size as I’ve seen in other Wayfarers); my World has larger Super-Chute ones. Which are not really as good, but the larger size does make them more effective.
