Hi Erik,
Thanks for the pointers. When you say mast track back, do you mean all the way back?
Have the boom quite low already, will ceck the length of my harness lines.
Don't have any pressure on my front foot when going half or downwind. To keep my foot secure in the straps I twist it a bit. Will try next time to pull up a bit .... slowly
See also that you use the smaller fin with 7.7, will do that too next time.
Again, I'm quite happy with the performance with my 9.0 (51.6 km/h), the set-up feels good an light. Just don't reallly get a lot faster with more wind and a smaller (7.7) sail.
But good tips, will try these!
