Have you ever seen this guy out at lowers on his single fin? I came across this article and 2 videos of him surfing. In the first one he does a 360 bottom turn and in the other video he just does air after air on a single fin! http://www.surf-hunter.com/2012/12/360-bottom-turn-on-single-fin/
seen this before... at first I was intrigued... now after watching it again... I feel like I know what it means for a board to have no drive in it. he looks like his speed is really at the mercy of the wave.
It seems to work well with a point break like wave such as lowers. I don't know how it will handle a beach break. definitely a very cool design, its very free flowy.
doesn't look like a carving 360 turn to me (as mentioned in the plug for his designs underneath the video)
those polfer-hull designs are really dumb, i think. But a real single fin, like the ones of the past...those things are ALL drive. Really fun boards. That thing looks like a thruster with one fin, and weird bottom design.
