Anyone with a view of the Hudson is in for a real treat. As far as spectator boats go there is a 'no nonsense' policy when it comes to areas for spectator boats. Violate it after a marshal has asked you to move & the higher authorities will be there to escort you away.
In Bermuda in October there was only one incident in a huge spectator fleet, see my link above. It was a jetski. Why does it always have to be a jetski rider? He was taken off his machine, put in a police boat & taken to a waiting shore party who transported him to a nice quiet place.
