Ernie here, this is something I learned from my coach Will Bush in the 90's and a short interview with Nate Smith about 9 to 10 years ago. It was reinforced when I coached a skier who on a great day run 38 off 50% of the time. When driving the boat he would slam the boat at the roll in and at the turn balls. The first thing we did was to change from a one handed start to a two handed start and progressively lean/load to centerline with 1 ball being a easy controlled turn. We worked on 38 off till I could barely feel him on the wheel. 38 off fell petty quick after that. 39.5 off brought the beast back, but after 3 weeks 39.5 fell. We kept on smoothing things out finding the perfect pickup point and progressive lean/load point. His first run we would treat as a tournament run, 28, 32, 35, 38, and 39.5 off with a 70% rate of running 39.5 off. Sig at the time was over 35 years old, had not been competing, speed 34.2 mph Zero Off. So 2 months of training and on this day in 2010 Sig is in the zone. I barely feel him on the wheel, he’s hitting his marks and Zero Off is happy. He has just stroked 39.5 off. He looks up at me and I at him. Set the rope at 41 off, and proceeds to run 4 balls at 41 off. I had to ask my spotter in the boat because I didn’t feel him on the wheel.
My first student when retiring to Florida I met while me and my wife were out on Lake Weir he saw me skiing and came up and said “I want to learn how to ski like you”. Craig was 43 at the time War Veteran suffering from PTSD. So for the next 3 years I worked with him and molded him into a skier. It was all free skiing training, trying to build a good foundation. Good times with one setback but no course skiing at all. When the day came, first time in a course it paid off. With Perfect Pass set at 32.3 he ran 15 off! Coming back another 15 off. Shorten the rope to 22 off, Bingo! He runs that. To easy, shorten to 28 off and he runs that!! Just awesome day with my ski Bud.
Remember that interview with Nate Smith? It was at a tournament in Michigan and I only asked him a couple of questions. I asked how do you make it look so smooth, you don’t look like you are working hard. His replay was “ When behind the boat I’m pulling my guts out”. That is the key, taking all these boats and Zero Off can offer to your advantage. This isn’t the 80’s where you could slow a boat down.
Since retiring to Florida I've been teaching a lot of newbies to ski. Because of that I do a lot of free skiing and to make my time more exciting I test myself by skiing 32, 35, 38, 39.5 and 41 off with control. (maybe not the width required for the course) The big thing is as the rope angle gets higher up on the boat, you better have your s?it together if you think you will turn and burn off the ball. The wall comes for me a 43off because of the line load coming so quick wanting to pull you sideways to the boat. That's why I say get out of the course and try it. You will learn so much. That 39.5 will fall for you.
A good one ball gives you Six
