I think I'm going to build one. Havent seen any that would fit well on my boat. I just need to build some sides and then I'm going to put my layout blind that I use for field hunting geese up on the front deck. I can fit 3 layout blinds between the front and back deck and one guy can sit down by the console without one so I'm figuring I can hunt 4 no problem but will normally hunt 2 and occasionaly 3.
