Here's a transition era hull, Punta Rocas, Peru, 1968. Leo Hetzel photo.
It's probably one of George Downing's boards, from the look of the fin. Dropped rails in the back, moderate hull in the front. Very sophisticated for the era. Felipe Pomar would be a good guess as to the board's owner.
Bitchin' car! And note the early use of canvas board bags...the first truly lightweight boards demanded them for travel.
The mid-70's Brewer rocker scheme worked wonders...not only for the contemporary single fin downrailer (as shown here) but hulls as well. The apex of the rocker curve was set well forward, and combined with a straight -- but relaxed straight -- tail rocker, it provided a loose but efficient platform.
Today's shapers would do well to reach back to this rocker and utilize it!
Not sure of the vehicle would get a parking ticket when the meter ran out....where would the cop put the citation???
