If you can come in from the river(boat) in the morning. You can sneak in behind the deer while they are in the field feeding. I use this with great success, I have a 12 ft john boat and a Electric trolling motor. The motor is important.
Other benifits are
No sweating walking to the stand
Not leaving your scent every where
I can hunt stand more than normal without ruining them.
No noise going to and from your stand.
