I handle the main on my Prindle 19 according to the situation at hand. Is my crew experienced? Is it very gusty? Am I tired after a long time in the wire fighting the heavy air? Concentrating on reading the gusts coming across the water and having an attentive crew cranking on the downhaul at the appropriate times goes a long way to allowing me to keep the main cleated when I need to give my arm a rest. However, there have been times when I wished I had arms like Hulk Hogan.
