Energy Surfboards was started in 1975 by Australian surfer and surfboard shaper Simon Anderson:
He is credited with the 1980 invention of a three-fin surfboard design, called the “thruster”, which remains the industry standard. — Wikipedia
There is no more collectible board from the innovation period of surfboard design than an early ’80s Energy thruster. — Board Collector
The Energy wordmark as seen on these boards uses the Stack typeface by Les Lawrence. It’s not clear who designed the logo. The accompanying “burning sun triangle logo” is credited to Hugh McLeod.
An article in Tracks Magazine fromFebruary 1981 (reproduced on surfresearch.com.au) includes a photograph of Anderson outside of the Energy Surfboards factory, 43 Carter Road, Brookvale. In the background, one can see a logo variation with beveled letterforms based on Stack.
