My last tournament was a Nationals where I ran into 38 off at 34mph. I just bought a boat and am starting over but now my division is 30mph. sloooow !
I remember goofing around with some friends skiing in the course at 30 mph at 38off many years ago it was like doing a deep-water-start on the back-side of each buoy.
If I skied on a 66" ski at 36 and 34 mph, what do 175 pound guys use at 30 mph? I know there are a lot of differences with different models, but does 68" seem logical for 30 mph ? I talked to one guy who is 82 years old and runs into 39 off in tournaments. He says the slow speed is more difficult because you sink so deep before you get back on a tight line on the back side of each buoy. I don't know how big a ski would be too big.
