Forget the laws, what happened to common sense.
Last time in the Georges, skiing, had a person in the water, when a jetboat with about 5 guys showing off their zig-zaging and speed (would have been about 60k's) aimed straight for the skier, only to change course within 30mts.
Not sure if it was deliberate and they thought it was safe to do so, or they just didn't see the person, but for a second my heart stopped. In any case they should have seen my boat which was about 25mts further away and stayed well clear.
Not to mention the jetskier that raced past me within 10mts whilst anchored at Como. They thought it was so Cool.
