There are two gates to pass through. "Touch and go" is allowed, and it's ok to cross again the gate in the opposite way once the gate is valideted.
In all cases, it is necessary to be behind the gate on the iteration minute (6 on this race) before going on.
!!!!! EDIT: the following is wrong, see next post !!!!!
Same for the finish line: if coming the opposite way, it is necessary to pass the line the opposite way, stay before the line on the iteration minute, and then pass the line the good way.
Best windsurfing to all.
