Doug, Trim the lowers correct first. The upper should flutter upwards on the windward side and flat on leeward. I don't know about the effect of fractionsl vs masthead. A great book you may want to ad to you sailing library is Sail and Rig tuning by Ivar Dedekam.

The mainsail I bought 3 yrs ago came with telltales about 9 inchs in front of the leech on both sides of the main. There are two pairs - 1/3 and 2/3 up on the leech.
I have been trying to adjust the twist in the main to get the upper pair flowing well on both the windward and leward side with out much success on the upper pair.
Is this the wrong approach? Would it be different for a fractional rig vs a masthead rig?
Thanks

Randy,
Place telltales at the battens off the leech of the sail. Usually good sail trim has the lower tales strait back and the top tale fluttering upward.

Friends,
Is there value in adding telltales to your mainsail? If so, where on the mainsail do you place them? Would you "read" them as you would read the telltales on the Jib?
Thank you, Randy Graves M-15 #407
