The name says it all, a spin on a classic longboard fin design intended for SUP Surfing. Not only does this fin offers a balance of hold and maneuverability, providing a whole bunch of fun in the waves, but it is also a great all round SUP fin that falls in-between the Halcyon and Tamahaac size wise. If your board has thruster boxes combine the Classic with side fins to fine tune your ride and shred the break.
