Re GB (and Chilly) - suggest that it may be helpful to have an event guideline that there needs to be 2m depth across the whole course area, and correspondingly more in wavy conditions to allow for troughs, and if this is not possible that the obstacle or shallow area must be marked and designated as an exclusion zone.
Running aground with kite up (and daggerboard down of course) is not a good idea!
