Below are excerpts from Mr. Karstan's essay relating specificly to his views on the gaff rig. To read the complete text click here What's the Ideal Sailing Rig?
Is the Gaff Rig Suited to Modern Cruising...?
If windward sailing is of paramount importance then of course the Bermuda rig has much to recommend it.
For modern day cruising the gaff rig is often maligned. In my view, for blue water voyaging the gaff rig has much to offer.
If a vessel's keel is shaped efficiently and if the sails are cut for maximum efficiency on the wind and if the sail plan has been designed well, a gaff rigged boat will perform incredibly well, in many cases besting the performance of
