NOTES

BOARD HISTORY
surfresearch.com.au acquisition, April 2006.
 Previous owner was Steve Jensen-Schmidt, Narre Warren, Victoria.
 Steve noted, March 2006 ...
I am not the original owner.
I swapped my board (An Island brand - from Phillip Island Victoria) for the bonzer when I was on
holiday with my mate in Pambula.
The guy who swapped the board with me was from Sydney.
I am pretty sure the year was 1975.
Previously I had surfed with a chap at Phillip Island who had come down from NSW, and he had a
Bonzer.
I thought his board was ace, and when the opportunity came for me to get a hold of one I
was really happy.
I am now 2 weeks off my 50th birthday, but I was in my day pretty slick on the board you have just
purchased. I hope you get as much pleasure out of it as I did those many years ago.

In response to my questions, Steve further noted, April 2006 ...

1.  I don't know about the green spray  - But I didn't put it there, so I am not sure if it original
2. The centre fin is original ( I did a crap job of fibreglassing it back in after I lost it hitting rocks at
Phillip Island)
3.  The leg rope attachment behind the fin was original to my knowledge, and was there when I got
the board.

COMMENTS
The board was possibly shaped by Bob Cooper or Billy Tolhurst.
The spray and glassing probably by Bob Cooper.
The banded spray design on the bottom has some similarity to the illustrated Mike E
aton model, below.
The board has been extensively repaired (poorly) and at some point the resin/glass leg rope attachment behind fin was added.
 
MANUFACTURER/SHAPER HISTORY
Bob Cooper had an indelible influence on Australian surfing and surfboards. 
He started surfing at  Malibu in 1952 and saw the sport before the onslaut of commercialism that followed the Gidget Revolution, circa 1962.
He worked for Velzey, Yater and Morey-Pope Surfboards, where he designed the Blue Machine (circa 1967-1968) that featured an assymetric fin.
In 1959 he made his first visit to Australia, followed by an extended stay 1964 - 1966 and permanent residence from 1969.
In this period he worked for or with Barry Bennett, Gordon Woods, Joe Larkin and Midget FarrellySurfboards, importing invaluable construction techniques from his U.S. experience.
Circa 1970, Bob Cooper started Cooper Surfboards at Coffs Harbour, NSW.
Other shapers at the factory included Billy Tolhurst, Ronnie Goddard,  and Richie West (USA).
Cooper Surfboards was the first Australian manufacturer to promote indigenous Koori surers, circa 1971.
The company was sold to Ritchie West, circa 1980 and in 1993 Bob Cooper moved to the Sunshine Coast, Queensland.

Apart from his surfing and board making skills, Cooper's dedication to the Mormon religion estabished an
unique profile in surfing culture.
Furthermore, as a student of surboard design, Bob Cooper collected several significant board designs -
which he left in California.
These boards are now held by the Surfing Heritage Foundation, California, and are online at... http://www.surfingheritage.com/bob_cooper.html

DESIGN HISTORY
Original design first shaped in December 1970 by Duncan and Malcom Campbell  (USA) characterized by forward concave leading to double concave each side of the centre fin with two keel- type fins set on the rails
(radically toed-in and cambered).
See http://www.bonzer5.com

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.

It was a (admittedly complex) combination of previous design experiments - multiple fins were first used by Tom Blake circa 1940, tail concave by Bob Simmons in 1950, tri-fins by Brewer in 1970, keel fins go back to Blake and were re-introduced on short boards in 1972.

While some commentators have seen the Bonzer as a direct precedent for Simon's Thruster, its influence was probably substantially less significant than Brewer's Tri-fin experiments (that critically noted that placing the rail fins behind the centre fin made it "track", when positioned in front the board was "looser"), MR's Twin fin, McCoy's wide tailed No-Nose design, and of course the direct influence of Frank William's Twin-fin with a small centre trailing fin.

http://bonzer5.com/history/timeline/1970-birth-of-the-bonzer/

A personal perspective:
I briefly rode a borrowed Bonzer in the mid-1970s, and like my contemporaries, found the board very stiff and with a tendency to hang high in the wave face.
A number of local riders actually sanded the keel fins off and thought the board went significantly better.
A local manufacturer picked up on this and produced a number of boards with the deep double concaves, but without the side fins, that were well received.
In my search for vintage boards, I have come across one example of a Bonzer with the side fins removed, so I assume this was not just a local phenonomon.

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.
