Google "jetski dock bumpers", lots of options, but depending on style of dock, they may or may not work. I always tie up my skis with ropes from both ends so they can bob and bounce all they like and hit nothing. This too only works with the correct tie off points, but I can usually make it work, even if i have to jump in to tie off a dock pole. Watch out for sharp objects though. Of course I ride a HX, and wife rides XP. Both around 9 ft. Good luck!
