After a couple of years of thinking about it and renting, I finally got myself my own kayak, this past
fall. I've had it out a bunch of times locally around Philadelphia and the New Jersey pine barrens. I got it in just enough time to take it for two Assateague camping weekends before Hurricane Sandy wiped out those campgrounds (since reopen, though!).
I'm developing a system that works for me, for doing wildlife photography from the boat. Maiden voyage in Florida over the christmas break with the plastic tote setup and 300mm hand-holdable lens was a big success. I picked Old Town's Voyager kayak for its side-to-side stability. It's not lightning fast, but it does what I need it to do: not rock a bunch while I'm pointing the camera at something. Second photo below shot from the kayak.
