Yes I do have the back for it too...although Sunday was the first time I actually used it and it was only for about an hour until it got entireley to hot in there. It has little bungee cords with plastic thingies on the end that attach to some floor mounted holders which I havent installed because I am not looking forward to kicking them with bare feet all summer just to be toasty the few cold days I use it.
I think if it was butt *** cold like in the 30's it would definitely be useful having a back but realistically I think the 3 sides is perfect for probably 98% of the boating I do.
