Not if you want to observe animal life too. Jet skis are very loud, and not all that comfortable either. You'd be better off with a flat-bottom boat, like in that one photo. Whether you have an airboat or a small outboard motor, they operate a lot more quietly and give you enough space to bring along whatever supplies you'd like.

Airboats aren't quiet at all.... maybe you mean a canoe/kayak with an electric trolling motor? Newer PWCs aren't all that loud as long as you aren't going full throttle.
