There's a huge difference between doing it on a 4ksb and an open beach cat. I've done a lot of racing offshore, and it's not too hard to push a boat 24 hrs a day when you can go below, get some hot food and catch some z's off watch. Doing that on a beach cat would be impossible...

Now if I can build a monster set of cat trax for the R33, and get a team of pushers - it's game on!!!
