I can tell this is not your first rodeo!! Looks great. I like the height of the sides. Keeps those buddies with prairie dog syndrome below the camo.
What do you plan to do for hunter access? Ive tried fixed ladders but that has its issues.
Even knee deep water puts the platform at waist high.
Can be a problem for us older guys when wearing the 5mm neoprene.
One idea you probably already know about:
I attached a 2" x 2'PVC pipe on one each end (vertical) and then "anchored" the blind by sliding a steel pipe through it and tapping it into the mud. One on both ends keeps the blind from spinning. The blind is free to slide up and down as the water level changes.
This is not my first rodeo but it is my second. The first floating blind I built was a month ago and I did not do anything special to it because I was worried about stability issues. After seeing how stable the first one was I was confident enough in the design to sink a little more money into this one.
I am not too worried about people getting into and out of the blind because the water in our reservoir is too deep to walk in for the most part. People will be dropped off in the blind and one person will park the boat and kayak back in and hide the kayak under the blind. If I had to get out of the blind I am confident I would not have any problem getting back in going up the dog ramp.
I also have not thought about anchoring the blind because it will be hidden in reeds that are so thick you can barely drive a mud boat through them. I don't anticipate needing any kind of anchor but I will probably weld some brackets on the back side for two posts just because I have the scrap to do so and would be kicking myself in the arse if I needed it and did not have it. I am glad you reminded me about that because I want to have everything I need welded on to the blind before I get it hot dip galvanized.
I can't wait to see this thing brushed up.
