Many racers want their equipment in top shape. Trailering wears your rudder hinge pins, rudders and transoms far more than most sailing due to the vibrations and the weight of the rudders in the "up" position-
What I do on my Prindles is remove the "hinge" bolt (1/4"), rotate the rudders so they are pointed up (about 180 degrees from the down position) and drill a new hole in the rudder head through the hinge bolt hole in the casting. No extra holes in the rudder casting, quick to put rudders from the "up" to sailing position, no need to tie/untie up and downhaul lines, load on parts reduced over that in the straight back position, rudders do not project behind boat, and looks "cool" with the rudders pointing up (friends have called it an "F 16 fighter" look).
