Most states require a three-seater for pulling tubes (driver, spotter, plus spot for person being pulled)
Honda Skis have near boring reliability.
If you want the Turbo model, look for the X designations in model name.
F12X = 3 seater turbo
R12X = 2 seater turbo
For $5000, you won't get two. But you can get new leftovers for near that price, that are a couple of years old.
I seem to remember that Honda recommends the non-turbo ski for pulling tubes/skis regularly.
