I had one of the original fat seats and blew the seams a couple of times, but a pool patch kit repairs even an 8 inch seam split
In order to get more weight into the back of my direct drive I filled the fat seat to the max, then filled a fat sac about 2/3 full on top of it. If we had more than three riders they flopped onto the fat seat with the sac as a back rest.
Edit: the weight claims are false and way under what they advertise. Do the math on gallons of water times 8.34 lbs and you can prove they are lying.
