A quick clip of Moritz Mauch on his 7'2" x 24" x 65 liters Gong contest SUPs:
- the new Alley (green)
- the Curve SP (red) it replaces as the "World cup" contest shape in the line.
70kg (but 21 years :-), and has been SUPing for 6 years. Lives in the Canary Islands, on the water 300+ days / year...

- Me on NFA 9' 120L at 100kg. Float-ability of +10.
- Moritz on Karmen 6,10 65L at 70kg. Float-ability at -10L.
I'm not sure everyone is up to taking on the challenge of the -10L because it's a real physical test. On the other hand it will allow you to put the Board into some wicked situations, and get out of them unscathed, that is, if you're Moritz;). 
With a little paddling speed, we can see how he pulls on his Paddle :
But while surfing he's like a cat :
He can almost smack it under the lip :
Without getting blasted :
