So Stefan, two quick points. 

1. Standing in the water holding the boat or anchoring is always legal. If you can use it to your advantage , that is fair. Any other boat can do the same.  Provided you comply with 42 and dont push or pull off, this is legal and part of sailing.
2. In real life, in good breeze, in the absence of a foul current, it does not pay to be at a standstill at the start. So this is all a bit academic.
Nonetheless even if there was a tactical advantage that I do not fully understand, it is legal to anchor.

Justin, it occurs to me that if F1 adopted redress, and a driver who was punted off the track by an illegal move got average points, race place at incident or whatever then at least one and possibly more Championships would have ended in different hands.
One may imagine that the knowledge that pushing an opponent off the track would give them points might have changed a  number of drving styles.

Doug ... I can't imagine why WS would have gotten their undies in a bundle if USS did an Rx.   It's clearly allowed without WS permission in 86.1(a) .. so I don't think reluctance due to what WS would have thought holds much water. 

No Flag does not = No Foul.
No Flag = No Protest.

If there has been a foul, there has been a foul.
If a Boat knows that they committed a foul, then they should take a penalty .  

I love this sport. No other sport has rules like ours.

Sounds like David implemented Rule 0.0  "Keep 'em coming back for more"
