Something different for W coast racers

There’s a JKK Supernova on eBay. One day left, no bids - for those of you who might like to add something a bit different to your fleets.

Boat specs/info here.

No connection to seller. Another odd one - I watched a Seda Spirit downriver racer close today with no bids (I could not think of a single excuse to even consider bidding myself, other than pick-up might have made a nice road trip):

and for the really adventurous …

What is that thing?
