The calculator called for draft (not including keel) but the formula called for draft at beam/b away from center line. Which when figured in on my boat would make my AVS 167.7degrees....alot more realistic than 193.
calculator used: http://www.sailingcourse.com/keelboat/cal__avs.htm
numbers used were beam: 8.75'
total weight: 15,000lb
draft at hull B/8 from centerline: 2.5'
ballast & keel weight: 4400lb
(4000lb ballast and approx keel wieght 400 figured on 31lb/cf for fir)
