Its not a SUP but I have also posted this in the SUP and longboard forum, It looks like a mini mal and it looks like he surfs somewhere near miami/mermaid a bit. Someone may recognise him...
Possibly more work than your looking for but maybe send the pic to the local rag with a bit of detail. Always good to see good news story's in the press other all the negaitive.
That will put you big in with karma. Call when we are going surfing next
