"This board manifested itself into existence as blindingly obvious next step for the SBoss. After riding the SBoss for about 18 months I realized how perfectly all the same outstanding design features of the SBoss would translate into a performance midlength.
The DNA of a midlength that fits into the Slater Design world would need to stand out in its look and be outstanding in its performance, paddling and diversity. Once again the rocker plays a key role in this shape and the experience I've had with performance LBs like the TJ Pro and V helped me tune the rocker that best fits the need for maximum performance without losing glide and paddle speed.
The board comes as a five fin but I ride it almost exclusively as a quad... the fin placement on the BossUp is adjusted so I can ride the same quads I ride in all my boards including the SBoss. "
