I've actually considered getting a trailer hitch just to make people wonder.

I can see towing a track trailer, but anything heavier than that would really worry me in the area of handling. The S2k is tricky enough as-is, no need to make things worse. And if we're talking jetskis, I hope you plan on having someone else handle the ramp for you...

 

There have been a # of threads on this in the past, worth searching to get more info.
