The experienced sailors here don't think that hooligans were required to make the wakes from all those boats go berserk. This video shows boats travelling in an orderly manner, but with only one thing wrong - they are going too fast.

I doubt if many of them claim to be real sailors. They are family people who take their boat on a big reservoir, and they don't go out when it's raining. That doesn't make them wicked people. It does make the people who organized the rally stupid people, however.
