Square One
40 years of R & D thruster
The "Square One" is the culmination of my 40 years shaping tri fins. In 1980 I saw Simon Anderson surfing Swamies on his hand shaped “thruster”. It was months before his Bells and Pipe victory and word travelled slower back then. 24 hours after seeing his design I drove back home to Northern CA and started glassing on center fins to my already completed twins. I made a batch of the first seen thrusters in Santa Cruz for the younger locals including Chris Gallagher, Mark Machado and Chris “the bear” Green.
