This was just a little fun stunt we did for easter. How to; to do the steep waterfall successfully it is about paddling solo and sitting quite in the back seat. Otherwise, the nose would dive too deep into the water to recover.
As preparation, we did nothing special to the boat. Temperatures were still around freezing. We checked the water before through probing a paddle on its longest setting, and Otto, of course, wore a drysuit and lifejacket with neoprene boots and gloves.
