The Phase Five Key Wakesurfer was originally designed by Sean Silveira to cater to his super technical riding. Coming from the Matrix, Sean decided to chop the nose and tail into a squared nub shape which makes it an inch shorter than the Matrix on each offered size. The Phase Five Key Wakesurfer delivers all the elements next generation wakesurfers are after. The Key rotates quickly and carries tons of speed through trick combinations thanks to its thin poppy core and subtle V-Spline bottom contours. The Key is constructed with Hybrid CarbonT material to take a beating. It is built with a single fin setup and loaded with our 1″ Skim Fin. It is the KEY for advanced riding!
