Haviing sailed on a Cat rig I found it can point to wind very well I think the problem for a sloop is the cut in the jib. I sail on the othe side of the bay from Judy (Oyster Point) and for me the wind is almost always from the West, so whenever I am heading in I'll be sailing to wind. after I experianced " in case something happens" which means my nephew in his quest to keep clutter out of the cockpit decided the lines would be out of the way by haging them overboard and one of the lines got caught in the prop. Yes I know I shoud have been more dilligent and checked for such things. Any way I tried to sail in almost made it until the Starboard fairlead broke and I was real close too! But unforunatly for us it seems our boats don't seem to sail to wind well under jib alone but sailing under the foresail is not uncomon when it's choppy this moves the drive forward and smooths out the ride alot of off shore is under for sail when it is too choppy so you wont ge too sick from hobby horsing.

The boats I've sailed under jib without mainsail wouldn't sail higher than a close reach. In my head, I agree too. I'd be amazed if the boat can tack tighter than 120 degrees under headsail only. But I could change my mind if I saw it with my own eyes or somebody got some real data. (From a technical standpoint, it's almost impossible for a mono-sail vessel to point as high as a sloop.There's a phenomenon called "upwash": the existance of a mainsail causes the airflow in front of the foresail to shift so there's a lift. In other words, without a mainsail, the jib is (relatively speaking) "headed". For more info, google "upwash jib" and/or "arvel gentry") But real-world measurements on a C27 would trump theory and comparison. Some compass readings and/or gps trail would do it for me.

This is considering sailing "in the slot" just below where she begins to stall. When going to weather a standard C-27 sails best slightly off or below this point to maintain drive, but you do need to use and control the main and adjust the backstay according to conditions.Dave HoyWYANOKEE #6295Camden, MaineJudith Blumhorst, DC wrote:> Chris,> > How high can you point a C27 with the 155 driving the boat and the > mainsail dumped?
