If you like jump shooting ducks it is a pretty good way to do it. I am sure you could also paddle out in the marsh and set up shop and hunt over decoys, too...

Good thing is you can get to hard to access areas. Places where there is no boat ramp close by you can always sneak a kayak.

Plus you don't have to worry about your engine not starting...or running out of gas...or spooking ducks if you creep up on em.

Cons are you got to paddle. And they're slow.
