Good one, Dean0!

 

When does the boat move???

 

Well hello there, charmer!
You know, you can't just sneak in here like that without an intro and cool pics of a Hurricane 1000...
Welcome to the cbr forum!

You don't need a bike, but it helps..

As far as the boat moving... well the trick is that there is no boat.
If you see a boat, you're either gay... or a lady..
That's the REAL trick...



I'm just kidding, you know... lol..

 

Strangest boat I ever saw. Must admit though. I think the design just might take off.
