On the 28R I sail on we leave it alone. The only time we ever play the daggerboard is when we are doing the Juanna's Regatta in shallow water (Navarre, FL). Which, we will do the distance race I am sure, but not the triangles in the shallow water. It is a pain to bring back down under load, and we don't want to winch it back down, so again, we just leave it alone.

Have a great day
