We had purchased the green 9' 4" (although it was listed previously as 9'7" @ the time we ordered it) boat a couple of weeks ago when it had been offered. It is NOT 38 mils thick as advertised (which was why we purchased it instead of a comparable model from another manufacturer for less cost off of Amazon). Instead, it is ONLY 33 mils thick. However, I will say that even though it is 'thinner' than what it's being listed as, it is still a very strong, and thick boat. We ARE very happy with it. Our kids have taken it out in our pond nearly every day since it arrived. It is much bigger than we thought it would be, and is also much sturdier too. It is very different than the cheap, flimsy kind of blow-up boats & rafts that are usually blue, and/or yellow in color. These things are really tough & very well made. I was very impressed by it over all. As to one person's question regarding the 'motor mount'. It doesn't actually have the actual motor mount itself, but does have built into it the connections that you hook the motor mount into. The actual motor mounts are an accessory that can be bought for roughly $20 on up online. With them you can actually attach either a gasoline motor, or a battery powered trolling motor. They consist of 4 metal bars that attach to the stern (back) of the boat. 1 on each side on the top, and 1 on each side at the bottom corners of the boat. Then they converge together on a board which they hold firmly in place, of which you can then attach your motor to. It is a VERY STURDY mount, and works VERY WELL. I cannot say enough about these Stansport inflatable boats, they really are great, and at this price, they are a really great deal!
