Hi - can someone please help - New R7 sail which has these creases in the luff pocket the whole length. Never had creases like these on the luff pocket on my other sails - just a batten tension issue? I haven't touched anything yet as its a new sail.
Thanks for any help.
All my wide luff pocket cammed sails do this to some degree.
If pushed lightly with finger in the middle of that area and the creases go away i would think that normal . The wind will push it in and make the desired curved foil shape ( now it is sitting flat ).
And also the mast bending sideways and the sail twist ( when in use ) should help that.
Its not a batten tension thing , that would only help on the outer curve side and even then you still get small creases.
There has to be some looseness in the luff pocket or the camms cant rotate.
