MANUFACTURER HISTORY Weber Surfboards (USA) :  Dewey Weber - flambouyant hot-dog surfer of the early 1960's Noted 1960's design : The Weber Performer with Hatchet fin. Early 1960's manufacturer, label still operating. March 1967 Nat Young Ski

The bottom design has  similarities with the shape of Rogallo hang gliders, first designed in the late 1940's as a method of recovering returning space capsules by NASA.
F. M. Rogallo predicted in 1949 that "Portable delta wings will give bith to a popular sport"
 - quoted in Desfayes (1974) page 41.
By the early 1970's, hang-gliding was a sport in rapid transition with a large amount of media exposure.

As a sign of the powerful influence of Australia in world surfing at this time, the name Bonzer (also Bonzar, Bonza) is an Australian expression for “excellent”.

In late 1973, the Campbell Brothers lisenced the design to Bing Surfboards for commercial development.
The design then became associated with Bing's head shaper, Mike Eaton, who had played a significant role in the development of the Twin fin 1 in 1970. See image and notes, below.
The Bing models were noted for the wedged Bonzer decal that was laminated on the side fins.

Australian exponents of the design included ...
Peter Townend (Gordon and Smith Surfboards). See image below.
Ian Cairns (Gordon and Smith Surfboards),  rode  a Bonzer to first place, 1973 Smirnoff Contest, Laniäkea , Hawaii and Terry Richardson (Skipp Surfboards). See image below.

Preceeded (contempoary?) by the Tri-fin of 1971, the design had some influence on Simon Anderson's Thruster of 1981.

Further adaptation in 1988, the Phazer - a Stinger/Thruster adaptation ( 3 similar fins with 2 small Bonzer D-Fins) initially credited to Rusty Priessendorfer for Rusty Surfboards (USA).
Later identified as another original design by the Campbell Brothers.
