Hide it best I can. I have a big camo net I'll use if it's out in the open. Try to get at least 100yd when water depth allows. I also have used it to keep ducks from landing in a place I'm worried they might want to.
Keep nothing in the boat that will shine or glare to spook birds...(don't keep a white yeti in you boat) I'll throw came life vest over something in the boat if I feel it sticks out but pretty much everything in my boat is camp/drab in color. we have beached the boat 20 yards from our blind if the cover is right. Sometimes it takes 100 yards or so. But here's a tip....ducks don't care much about a boat that beached and not shining like a neon light. Their habitat is constantly changing and that big log is just part of their world. But them sumbitches will flare if your ugly mug is shining! All while your $25,000 rig is beached 75 yards way and alls well with that.
