There is a previous recent post that addresses this, but the consensus was basically...
1.) Hunker down in natural cover and hide you boat away from you. I recommend that it be out of the line sight of birds working your dekes from over the water. I love to hunt out of my boat because it is so comfortable, but I flare birds most of the time when I try it. It is hard to hide a predatory monkey and big chunk of something "not natural" in the same place while still staying within range of your dekes.
2.) Even though it is away/behind you, hide you boat well. I like a camo boat covered with camo cloth brushed in with natural vegetation and pulled up in tall cover. I don't think there is such a thing as "too camo'd" unless it sinks your boat. If you lose your boat in the dark, it is just about right.
