About midway through our journey, our boats pulled over onto some rocks and i'm thinking, a bathroom break, what great timing as pee was about to come out of my eyes. Alas, it was not an official bathroom break, but instead everyone had to get off and walk about a half mile so the pilots could navigate a stretch with two gnarly rapids. The photos don't do the skills of our piloti justice. These boats are very long with a propeller jutting off the rear of the boat at the end of a 6ft long drive shaft which is attached to an 8 cylinder car enging which is mounted in such a way that the pilot can swivel and swing in all directions. And it ain't light. To watch these boats turn almost sideways to negotiate a bend, then snap through 180 deg to avoid the rocks and round the next corner was something to see. I think that myself and fellow passengers had one eye on the boat and one on all of our luggage which was still packed at the front of the boat, doing a mental checklist of what wouldn't survive if wet.
