I have a small boat (1436) that I keep my gear in, but I don't hunt out of it. It's just used for transportation, and for a dry place for the dog to stay if I'm standing in water while hunting.
There's usually 30-60 duck decoys in my boat, and a pair of canada goose floaters. When I approach an area that I'm going to hunt, I set the 2 geese out about 50-75 yards away from where I'll be standing, then I continue motoring the boat to where I want it to be. The rest of the duck decoys get placed much closer to where I am.
