Hi Steve, Along with other boats, I’ve been looking at a 47-foot ketch that has 454 sq.ft. in the foretriangle, 416 in the main (only one set of spreaders) and 182 in the mizzen. As the mizzen represents only 17% of sail area, by your recommendations on pg.645 of the Encyclopedia, this sail is more decorative than useful and the boat would probably be better rigged as a sloop with a removable inner forestay. If the mizzen were removed and a second set of spreaders added to the main mast to support the inner forestay, could this boat be expected to sail just as before? Or, is it more likely that the main mast would have to be moved aft and both the main and headsail be replaced? Thx for your comments, DM
Without seeing the lines plan and rig drawings it is hard to give specific advice. However, in general, from the proportions you mention you will probably be net faster in most conditions without the small mizzen. Second spreaders are usually not required for a cutter stay. However, running backstays usually are needed to offset the forward thrust. I’d check with a local rigger or spar builder. Good Luck – Steve
