It does have an advantage in that you can keep your beer inside (looks like
there's room for a cooler) and if you get drunk you won't fall off like you
would on a jet-ski.

I have the video for these things (free from the site) Its $2999 US.
They show a guy standing up, with the boat faced upstream and the thing
throttled to keep him in one place. The guy is fly fishing. I,
personally, would not try this. On the other hand, I see this as an
excellent tool for waters like the Chesapeake and some of its tribs
(i.e. the tribs are called rivers but on the Chesapeake, the turn into
huge back-bays). The 6 hp Honda engine will run for 8 hours on 3
gallons of gas (their claim) and the whole thing weighs 100 lbs. The
engine is supposed to be very quiet (which is all relative).
You could have a great day chasing stripers in a boat that you can put
on your truck or suv roof rack. On bigger rivers like the Columbia and
the Missouri, this could be a lot of fun chasing salmon or smallies.
Now we need to combine this with the pedal mechanism in the Hobie
Outcast and you'ld have the perfect, one-man flyfishing boat. Engine
off, paddle around and fish, engine on, move from hole to hole. This
would be great in the Baltimore inner harbour (great striper fishing),
where you need some extra speed to keep you from becoming a speed bump
for the tankers.
Its intriguing. If anyone would like, send me one and I'll put it
through its paces for a year or two.
