I had a few of these and I am a 33 too. The leg strap on the xl & large I had were the same length. I used the large with comfortable results. Take the harness to a sail or Bimini top place and have new straps sewn on. I didn't fasten the Velcro until I was on the wire because it wouldn't allow me to bend forward without squeezing my ab area. I felt very stable in the DK harness in chop and on longer trips, but for small chop and shorter trips I just use a old Nacra bucket.
