Bill Roberts has a tall and a short rig. He uses the short one in the Mug Race and the tall one on other races. We only have one rig, the short rig. It is 41.5'. Add to that the freeboard and we end up just at or under the 44' limit imposed by the race committee for the south course. The Shands bridge clearance is 44' at high tide. Everytime I have gone through it has been at least 46', plus an extra 2' in the center(or so the sign says).
We do not have a masthead spinnaker on our rig, nor a gennaker, like the other two RCs. Also our spinnaker pole is 3' shorter. That is the 20% sail area we give up. It is mostly downwind sail area, but that gennaker is a very versatile and powerful sail in light wind.
