I've seen a few of these here in North Carolina. They all were set up just as described above. What I think would be an interesting take on the pontoon boat concept, would be to station 3 or 4 field layout blinds on the pontoon platform, surrounded by marsh grass camouflage. That would give the entire blind a very low profile, perhaps lessen the wind resistant and eliminate the "Sail effect." Such a blind would, in my opinion, mimic a small marsh island.
