The Pororoca is a tidal river wave is generated by massive tides on the Amazon river in Brazil. The wave comes in from the sea and funnels down the river creating a tidal bore.
The wave can be ridden for more than 30 minutes and travel about 12 km.
Sheeesh... one wave and you can probably do more stand-up time on a wave than most folk do in a lifetime
