John, thanks, that makes a lot more sense. I couldn't imagine the sail area being that different on the two.
Also, I'm not sure if this should be a new thread, but...
I understand how a staysail could be really beneficial on long offshore passages. An extra knot or two over a few weeks journey, another way to balance the boat with less sail area up, if you want to drop the genoa, etc etc etc, but I know from experience what a pain tacking a cutter rig is.
I believe that the PS 31 comes in either cutter or sloop rig. I've heard of boats that have a "removable"? staysail, which is to say that the staysail stay unclips from a point on the foredeck and attaches somewhere out of the way for near coastal and channel work, effectively leaving you with an easy to tack sloop. Do many boats do this? Does it work without doing horrible things to the structural integrity of mast and deck? Other advantages and disadvantages of this type of design?
