I think your mast rotation has a lot to do with your upwind performance. At Grafham I thought you had the edge on me in pointing/speed ability but prior to that I felt more confident in my own boats performance. I put this down to your mast rotation being better tuned bearing in mind you have a wing mast compared to my standard section. So in summary I believe that if you have a wing mast you have to play the rotation a lot more than the standard section. The good 'A' Class sailors and some F18 Sailors are getting this additional tunning down to a fine art and I suppose it wont be long before the F16's follow suit. Although, for me it just seems like you can gain as much as you lose by having the rotation just right or badly wrong.
