A cat sailor I know told me this story about this scene (and i'm pretty sure i've mentioned it on this forum before):
It was filmed off Roton Point in Rowayton, CT. Upon capsizing a jetski was to tow a float under the mast to prevent the 60ft rig from turtling in 40ft of water... the jet ski was late, the mast turtled and the film company had to shell out the big bucks to replace the sails, battens, and etc.
I believe that Rick Bliss of New England Catamarans was on the boat that Brosnan was not. He's out of the country until the 22nd, but i'm waiting for an email back from him and when he gets back to me i'll ask him if Brosnan was on the rack or not.
