5'11'' x 20" hull with a huge fin and a pulled-in nose.
From Glenn and Nat
The Keyo Nat rode at Malibu in the summer of 1968 was 7'11'' and either 21" or 22" wide. Greenough drew up the template and sent it to Nat, and George later said Nat made it an inch narrower than the template. I think it was drawn out at 23" and built at 22", but it could have been 22" and 21" respectively.
Greg Liddle, about 6 years later. A refined, toned-down interpretation of Nat's Keyo. 7'1' x 22.5". The wide point wasn't as far up as on Nat's board, and Greg's outline had a friendlier curve in the tail. Greg rode this template for nearly 20 years.
The Orange Crate
Sam Model, originally built for Matt Miller.
9'4'' x 22 1/2", high density orange foam and redwood t-band stringer.
Named by Matt after the legendary dragster.
Early Greenough Tracker
This is a board George shaped for Chris Brock in 1969 under the San Juan label. It's a good example of the "Tracker" outline that was becoming popular in Australia at the time.
