To answer your question, I do think dagger boards would create more lift, but not sure if they would benefit on the broad reach max speed without lifting them. The centerboards do create a well balanced boat and you would most likely need to adjust the daggerboard location, fore and aft, to be able to take advantage of the increased lift....
