Hoop,
Congratulations. These kind of look like Bonzer fins but used in a kind of quad or reverse formation..... see what I mean as shown on the Bing surfboard below:
"Bing Bonzer...original 1973 round nose....Looks like a 73...in decent shape and looks like a real fun rider! Nice logo, really cool fins, and some extreme concaves. The Bonzer was designed and created by Malcolm and Duncan Campbell...they went to Bing Surfboards with their design in 1973. Mike Eaton, Bing's main shaper at the time, was shaping them and Malcolm was putting in the concaves...really progressive for its time..."
Were you inspired by these type of fin set ups ?
There are a lot of surfboard retro revivals of this concept... Interesting to see these now being taken up here in windsurfing......I remember something like this from Windtech in the early 90s......well done for the new slant on it.
Is Nude the only one doing these type of Bonzer tri and quads now?.. Is a trailer fin a Bonzer with less of a slant/angle ? It would be interesting to hear your thoughts on the matter.
Cheers, Richard
