Catalina 30 - Tall or Short rig?
I have a Catalina 27 Tall rig and would not own a standard rig(where I live). I race regularly and there is a major benefit to the tall rig vs. standard. From time to time I will be overpowered upwind but with a little mast bend or by lowering the traveler to leeward it''s an easy enough fix. But off the wind having a tall rig makes all the difference. With the tall rig you also get a 4'' draft wich also helps upwind performance. The standard rig has a 3 1/2'' draft I believe which hurts you upwind compared to the deeper keel.
By the way...I sail in Fl and can''t comment on the Lake conditions but I would say go with the tall!
