Marc Andreini Bonzer: Alternative Tri-Fin

Another cool Andreini up on Craigslist! This is a 6′10″ Andreini Bonzer shape. Bonzers can come in a wide variety of setups, but as you can see in the pictures above, this board has two side bites complemented by a large fin in the center. The fin setup is unusual for Andreini, whose focus is largely on single fins. With that said, Andreini is a noted surf history buff, and one whose designs draw upon the tradition of many other California shapers, like Reynolds Yater.

The board is described as being a “Campbell Bros Tribute.” The Campbell Brothers invented the Bonzer tri-fin setup in 1970. Simon Anderson invented the Thruster in 1980, and Anderson is widely credited for popularizing the tri-fin setup as the default for performance shortboards. That said, it is worth noting that the respective Campbell brothers and Anderson designs are very different, and the Bonzer, while not quite as revolutionary as the thruster, is a design that endures to this day.

The Andreini Bonzer pictured above was taken from a Mike Eaton outline. Eaton was shaping for Bing Surfboards during the 1970s. Bing and the Campbell brothers collaborated on a Bing-branded Bonzer model starting in 1973. Eaton, who was then one of the head shapers at Bing, was critical in helping get the Bing Bonzer off the ground. Eaton later went on to shape under his eponymous label, where he shaped Bonzers until his untimely passing.

At $700, the Andreini Bonzer isn’t cheap, but it’s a cool and unusual board, and good luck finding any Andreinis for that much cheaper.
