It will likely be more tender
The tall rig is 2ft taller than the standard rig. This results in a taller main and jib with corresponding increases in sail area and most importantly, the center of effort of the sail plan will be about 6 to 8" higher off the deck. As a result, in all conditions of wind, you will heel more. More sail area translates to greater wind force acting on the sal plan at a point higher of the deck resulting in an increased moment. Since this boat seems to sail optimally at about 20 degrees or so, more heel means a larger wetted hull thus more friction and an unlikely increase in speed (which is what I assume you're after). Of course, to reduce heel, you could weight the centerboard, but that introduces an entirely new set of problems. I'm not saying don't do it, just don't do it blindly. In our marina, several persons have shortened their keels (same result as taller mast) due to shallow water in Sandusky Bay (and the marinas) on Lake Erie, but the marina runs the modification through a naval architect to ensure it's OK. You might consider the same before going through the expense of new mast, new standing and running rigging and new sails. Russ Marcks
