Just a guess, 

 I'm thinking if Alex and Armel know they will be short jibing the ice limit for a while, with only a few hours between jibes,  they will not be making the full stack transfers below.

more than likely balancing the weight down the center and working the cant for trim.

 

  they are vmg running in relatively moderate breeze, 13-15kts,  so not as much speed loss compared to the energy loss in doing a full re-stack every jibe.

"The port support line knot suddenly slipped"

 

  did you guys miss this somewhat important starting sentence of the second paragraph?

 

  The ed mentions no one at fault, but i seem to have a different opinion.  You see, knots don't tie themselves,  

  and the wrong knot was used if it slipped.

 

    There's your at fault party...

All good in theory until you sail actually sail a real moth with the gearing adjusted right up. Going thru 2 or 3 powerboat waves feels like jumping speed humps in a car park. Put the wand behind the foil and the bumps would come after you have already passed them.
Fractions of a sec might sound insignificant, but lots happens in that time and when you are tuned into it, the fractions of gains all add up.

cool,
 
the question I have is, is it better to go over the speed humps or is it possible to go straight through them
I know in boarder cross typically you try to keep your CoG moving through a bump (letting your legs flex to maintain as near as possible a constant velocity through the bump). Is there any merit in the idea of trying letting the foiler stay straight as the wave passes through rather than moving the whole mass up and down as the wave passes. I'm assuming there are significant risks with this as well, and again it may depend on how the foiler is intended to be used.

That's exactly what a wand does.
For some reason there is a misconception in this thread that a wand is for handling wave management, that is not the case.
The wand handles height management independently of wave action.
When the hull is waterborne the wand tells the foil to creat more lift by trimming the flaps down. The opposite when the foil rides too high to the surface. It auto levels the ride right where it should be.
this is true in both flat and choppy water.
