Standard VS Tall
I owned a 1984 C25 tall rig, fixed keel model for a number of years, and raced against standard rigged models on occasion.The tall rig C25 has a mast that is two feet longer, and the boom rides one foot lower with the normal mainsail. If the mainsail is cut generously, the boom can be a bit of a head knocker.The tall rig is slightly faster in winds under 15 knots, and will pass a standard rigged C25. In winds over 15 knots, there is no difference in speed, but the tall rig should be reefed or switched down to a 110% jib by the time the wind speed reaches 18 knots, which would be a little sooner than with a standard rig. Of course these are generalizations depending on the sails and setup of individual boats.Neither boat has any other handling idiosyncrasies that I am aware of.
