well, it depends on the foil you get if you get the 150 yes the waist is only 79, but if you get the 182 the waist is 87. Now if you are going 150 armada doesnt make the AR6 in a 150 you would have to get the AR3 in a 151, waist of 74, but again if you get a bigger ski, the waist will increase, so i would look at the right length first then worry about the waist you want
