I stand corrected. For the carbon T, class rules state:
Mast Length - -
Upper point height - 9294 mm = 30.49' Note this refers to the upper measurement band max height (head of sail cannot be above this line), not the overall length of the mast.
I think I was recalling the dimension between the upper & lower measurement bands, which is 8915mm or 29.25'.
Not sure where the 29' measure comes from on the T mast. I measure from the top to the bottom of the mast section (not including the base) of a marstrom untapered aluminum section, 30'- 10 3/4". Now the luff of the sail may be around 29' but mast is about 31'.
The T chute and the N-20 chute may be the same area but the N-20 is a class sail built by one manufacturer. The T sail can be made flat or full and by anyone as long as it measures in.
