The New Phase Twinzer is a High Performance Short Board with a twinzer fin set up and dual channels out the rear. It has a fin box in the center rear. The aggressive rocker coupled with the twinzer set up make it so you can get more radical in smaller weaker waves. Or, add the nub into the equation when the waves are steeper, and you're as stable as the guy with the thruster, only you can paddle faster and catch waves easier. The one pictured here is a "Oak Standard Construction" 5'6" x 19.25" x 2.375" for a 5'8" 150lbs rider. Can be made in any dims for any rider skill level.
