New to the water

[Dgiglio3087]

Hello all, I'm new to the kayak/canoeing world.a prospect if you will. I've been thinking of purchasing a kayak or canoe to use for photography. But I don't know which one to go with. So here's the traits I'm looking for in whichever watercraft I choose. The first one being stability, ill be on the water with a pretty expensive camera set up($2000+),though while im traveling I plan on using dry boxes. The other thing is that I do not have a truck, I have a compact car so it has to pretty portable. I was looking at something in the 10' range. I've never used a kayak before but I've heard that the wider the more stable, and that the sit on top kayaks aren't as stable as the kind you sit inside, is this true? I have used a Conoe a few times, and I like the canoe. By the way whatever I choose will be a single and not tandem . Also, i mainly plan on using it in still water, bayous, swamps, the fastest moving water being the pearl river. Any suggestions for me?
Thanks in advance!
