Sam,
The Canadian military uses helicopters with those colors to do search and rescue missions (CH 146 Griffons), as do a number of other countries. Might be some snowbirds down here participating in some SAR training. I was over that way today for the boat show, but didn’t notice the helicopter. Another thought might be a private company or SAR group doing some product or training demonstration going along with the boat show. If I see the copter I’ll try to get some info on it.
At least it’s not a black helicopter. 😉
