Twin with stabilizer/trailer fin
Okay, if you’re going to choose a twin with a trailer, basically what it is it’s your base is your twin fin setup. Basically you have your big side fins, that are bigger than your tri-fins. And then sometimes on a twin fin, you kind of get a little slide into the turn, for on those bigger days you need something more to hold the tail down and give you more of a positive traction in your turn. So basically, what they’ve done, is you still have your side fins as they’re holding into the face of the wave, and then you have a small trailer fin in the back that is just holding down the tail just a little bit so that you get that positive feel as a thruster, but still you get the speed of the twin fin.
