It depends on the boat... we have a cabelas northern flight blind on my 17ft. boat with the added windblocker material and quick-flip top. It took a day to build, but it works great. Provides complete concealment. Comes on and off the boat quickly for fishing trips because it attaches with only 4 c-clamps. We also have a small beavertail sneak boat with the small beavertail blind but we haven't hunted it yet so I can't comment on it yet. Seems ok though.
