[Paddlewise] "Extreme" Kayaking??

I just received my first issue of a magazine from National Geographic,
called "Adventure".  In it -- wish I had it with me to properly describe it
-- there was a brief article on an island near one of the Atoll's off the
coast of Belize.  The article covered numerous reasons to visit the island.
It included an underwater picture of a kayaker wearing a diving mask and
snorkel.  The Kayak(er) was completely underwater, almost perpendicular to
the bottom, with the bow a scant few feet off the bottom.  Couldn't clearly
tell how far under water the stern was.  The caption mentioned "extreme
kayaking" (I think - I'm at work and it just occured to me to ask the
Paddlewisers about it, so I'm drawing from memory), but the article was not
about kayaking specifically, just travel adventures and a variety of things
to enjoy while there.

I've not been Kayaking long, but that photo caught me by surprise.  What's
it all about??  Anyone familiar with it??  I have no intention of trying
it..... just curious.

normal launch sites are frozen)
