Anybody own or have used one?  Do they work as advertised? Where did you buy it from?  A friend is looking at getting one to push his boat in the garage because there is only 1-2" clearance from the gate.

is this what your talking about..?

I had one for the same reason ..
I would keep my pair of jetski's at my dad garage.. was easier to unhook then walk them in..
his thinking was if your using my garage I aint moving my truck..

Worked great for me, but I never tried it on a full size boat..

hope that helps...  

oh yeah I bought same place I got my jetski's... seen them every boat store I go into..
