Open Water at NC:
You are the Foreign Judge at a CSIO4*.
During the 2nd round of the Nations Cup, it becomes very obvious that the horses have many more problems to jump the water jump than expected. It is not dangerous, but in the end approximately 50% of the horses have faults at the water.
After the 1st round, the question comes up whether it is necessary to keep the water jump as it is for the second round or if it would be possible to make some changes.
What is your proposal and what Rules or procedures have to be followed?
