Towing a tube....
The XP has plenty of power to tow a tube, engine wise. What it lacks is a rear facing seat for an observer to safely sit while towing. For this reason, there is no tow pylon (attachment) for this ski available.
In most states, it's against the law for a two seat ski to tow another person. I'm not a stickler for the laws and would probably be the first one busted doing it, but I would probably give it a try. But, that is the reason Seadoo didn't install one. The two loops Karl is referring to is the tie down anchors.
Good luck, let us know how it went. If you tow a tube and make a sharp turn, the tube is going to fly out with such "G" force, that it's probably going to yank you out from under the ski.............:rofl:.........that sounds fun just thinking about it!.........
