I think there was a lot of luck involved...
Riders reported kites falling out of the sky passing behind the big ships...those big ships cannot stop...they need about 3km to stop!
And I am happy, I am not the only one anymore in front of a big ship...had that situation in 2000 in the bay of Palma (Mallorca, Spain). It was the first time I was standing on the board and riding...of course I didn't want to stop! Just made it in front of the big ship, the wind got less, had to sinus the kite...but made it. The captain gave me the idiot sign...but hey, I was riding
But could have been really bad if I dropped my kite right in front...luckily nothing happened!
So, be aware of the danger going in front or behind the ships...rather stay away!
