My mother picked up an '04 Honda Aquatrax early this season. She seems to really like it, but she is in her mid 60's, lol.
She needs to bring it down to the surf, or maybe not!!
I've ridden a Honda (R12X) in surf and didn't care for it at all.
It's too big to "safely" get big air on. If you take off wrong, it starts pitching and there isn't a thing you can do about it.
