Hi Rolf,
I think my mainsail was a special order from the local agent to E/P, although I was never asked my weight, wind condition,etc. I have readed on another thread, you mention 10-12% for chord to depth ratio. Is 10= flat, 12=full? What about the location of that maximum draft, 35%? Same location troughout the sail?
After the sailing season, once I bring the boat home, I would like to play with the spreaders and diamonds adjustments trying to match the sail-mast and I start to believe that chord to depth ratio is probably the ultimate result I should look for. Am I wrong?
Thanks for your support

Denis
