YIKES. I am reading these tension numbers, wondering if this is part of the reason that my chainplates were broken when I bought my boat! I am using 1300 on the uppers, 1100 on the lowers, and up to twenty knots, the lowers do not slacken, so this base setting may even be too tight. I do not carry my 163 above 15, I found that my 140 is faster, flatter and higher in winds over 15 kts, so that may explain my ability to carry a looser rig. No problem with the bubble in the main either. Maybe this is a carry over from my J-24 days, as the number one in that boat is a 145%. Have not tried the light air settings yet, as central FL does not have much light air in the evenings when we are usually out, but if we have a drifter, will probably try 1000 lbs on the uppers, 800 on lowers. Recommend if you use settings over 1500 to check the rig on cold days, as the tension will increase!
