Heres a couple of Quatro photos of what Keith Teboul is riding. Its an 8.0, not sure of other dimensions.
I have the production 8.6 Quatro and have surfed it a couple of times so far in shoulder to overhead conditions. I'm playing around with fin set ups, but so far I like the board! I'm 6'5", 205 pounds and wish the 8.6 was a bit narrower and lower in volume (maybe 29 x 115L) for the glassy days, but its volume and width are a blessing in messy chop/wind. Can't wait for the next swell!
the guy holding the board looks like a skinny little hobbit....not suitable for "big boned" people in lumpy wave conditions perhaps?
