My 35 MKII works best when close hauled if the first third of the mainsail is luffing, so I mostly always have the first third of the main from the mast back luffing, that is faster and less heel on Alianna, for good upwind speed heel angle 15 to 25 degrees is good...the main works best upwind with the top 2 tell tales streamimg straight back; I drop the traveller below center line in apparent winds above 17 and I fallten the main by increasing outhaul tension when I drop the traveller. I only have 2 tell tales on my mais sail for good reason...it's a 2 plus 2 batten main with loose foot and high roach...mine is high aspect ratio with an open foot on the shorter boom at about 12 feet...it's a good sail but rig tension needs to be right for best performance. I have end boom sheeting with a bridge deck traveller and traveller and mainsheet adjsutment in reach from the helm station for single handed sailing...I have a Raymarine wind system, a cockpit mounted inclinometer and marked halyards which allow me to sail by the numbers...after some time with the numbers I can now do it mostly by feel, at least in our Bay
