Ok, time to resurrect an old thread that has come full circle
I remembered reading this and commenting on it a few years ago, so I came looking for it.
Since landing in Cedar Key, we've had so many people visit and ask about photography specific boating tours, that I had the same idea you did Chris.
I recently passed the Coast Guard test for a Captain's License and we're in the early stages of putting together some Birding Specific Tours around our area of the Gulf Coast.
Chris, you'll have to come over and take one of our tours. They'll be small, hopefully kept to 4 people on the boat. I'll work with each person to make sure their camera is set up properly and explain some tips on how to come home with images they'll be proud to show off to their friends and fellow photographers. We're planning for opening up the tours for the 1st week of July when the island of Seahorse Key opens which is a Bird Rookery. Tours will be 4 hours starting as Sunrise and ending when the light gets too hot for good photography.
Last year we were able to get some top notch images day after day.
