I retrofitted/modified one on my old layout blinds. Cut the floor out, attached a couple hard points for the support and it has worked like a charm. Takes about 5 minutes to set up/tear down. I used some marsh grass from Cabelas to brush it in ( dyed it to match my local marsh ). I fold the blind, lay it on the canoe floor and load up my decoys on top. Pup rides and hunts from the back.
I use an Old Town discover solo sport canoe but this could be easily done with a larger canoe. Just need some pre-brushed light camo net to fill in the larger gaps. This setup lets me effectively hunt tidal estuary's where there I have to move frequently to chase falling tides and little cover and too much water for a traditional layout.
Can tie off to a log for support or I use 4x 3' wood dowels I drive into the mud "like spuds" and tie off to with bungy.
