  1. My guess is you kicked yourself with the heel of your front boot when releasing based on there being no blood and the use of a rear boot delaying release of the back foot. A release cover wouldn't have helped in that case.  Most people concerned with kicking themselves use a shin guard on the back leg, but that unfortunately wouldn't have helped in this case either.

  2. First attempts at the course on the Skat (the middle one in picture above).  I'm not sure I have it set up right. I measure the front binding at 17-3/8. Fin is 7.562L x 4.187D and .750 dft.  Anybody have other settings I can try?

  3. David Akers at 5'10" is to the point of running into 38 off after 4 years. Imagine what a retired basketball player like Yao Ming might do.  We need to somehow challenge some of those giant 7'6" ex-pro basketball players to start skiing and get to and through 43 off. 

  4. It was great to see SIX different trick ski brands on the podium- D3, Quantum, Reflex, Radar, KD, and Goode. I'm happy to see a resurgence of interest in tricks. I'm going to need other trickers to ski with for then next 60 years or so.

  5. "I’m sorry but I couldn’t find any information about Joel Howley’s front ski boot stiffness. However, generally speaking, how much volume of the ski boot a person’s foot takes up will affect leverage and ultimately how stiff or soft a ski boot feels. Generally speaking, the less volume of a ski boot your foot takes up, the softer the boot is going to feel1. The boot fitter will usually observe the skier flexing a boot and may make a judgment to either recommend a stiffer or softer flex based on their observation in the shop2." Maybe ask @JoelHowley's bootfitter😉

  6. I would like to put forth two more thought experiments.

    Let's assume the length of the line is approaching infinity, thus theta approaching 0deg.  @Bruce_Butterfield you can still keep it tied to the bridge abutment if you want.
    What is the length of the skiers path?  The potential path approaches infinity, but what path would a skier take through the course? Take 41 feet off that line. Now what would the skiers path be?

    Now assume the the length of the line is approaching 0. Closer to 0 would yield a skier path closer to the boat path, approaching 259m.  

    My new conclusion is - I  don't think the answer to this question is going to help anyone add balls, but I am grateful that slalom gives us this stuff to think about during the off season @Hortonprovides us the place to talk about it.

     

  7. The boat is traveling straight down the course at (15.28 m/s) 55kph for 259m.

    Skiing precisely ball to ball would be a distance of  293.75m, so an average speed of 17.33 m/s.

    If you could ski a perfect square wave ball to ball you would cover 397m, and would be going 23.42 m/s.

    The further you ski outside the balls the further you travel, and therefore the faster you go.

    As the line gets shorter, the distance you can travel beyond the ball line gets smaller and you are getting closer to skiing ball to ball.

    Conclusion- believe what @MarcusBrownis telling you!
