You're looking at a helicopter buzzing past a ketch anchored behind us in Portobello, Panama. Click to enlarge.
Because of the TV camera we saw mounted to the bottom front of the helicopter...and the fact that it was setting up and then "chasing" a guy and a woman riding full speed in a panga toward the Spanish ruins of the north fort (you can see the panga's wake in one of these photos)..., we guessed someone was filming a segment of some TV travel show or whatever.
Chopper Pilot Dude was flying BETWEEN SAILBOATS AT ANCHOR. In 20+ knots of wind. And it's tight in here - the boats in the Caribbean don't leave as much space between them as boats do on the Pacific side. We saw Chopper Dude do his first dry run OUTside the boats at anchor (i.e., next to The Fox), and almost lose it in the crosswind. And then he gets comfortable and makes a dozen passes in between various boats, lower than mast height and no doubt looking for Awesome Camera Angles. At least he didn't hit anything, so I guess he knew what he was doing.
The things you see while cruising.
Can anyone tell me what TV show he was working for? Were we on TV? Hmmm?
