Last spring I sewed up my own cover, replacement of the old, not too hard to do, 150-175 $ in material. Regardless below are some numbers for you, it fits the sail a little tight, which is the way I wanted it.
Over all length 128 inches
Height starting at the mast, first measurement is how far back from the leading each of the mast(the zipper used to close the cover at the front end of the mast) The second is the height, all in inches
0, 48 (zipper height)
10, 48 (to make room to wrap cover around mast)
25, 26
36, 21
48, 19
60, 18
72, 17
84, 15
96. 15
108, 13
128, 10
The above measure measurements have worked well for me, with that said if I were to do it again I would increase the height at position 25, 36 and 48 higher to allow for the sail "stacking up" at the mast. An increase of at least an inch.
