This thing is AWESOME and seriously the best purchase ever.  We don't even have sand in it yet, and it's a huge draw in the backyard for both kids & adults.  Unfortunately our hardware packet arrived open with screws, washers, and nuts scattered everywhere in the giant box and it took us forever to find them all.  Also, the sides at the very back of the boat seem quite flimsy and look they will break sooner rather than later.  That being said, this thing rocks!
