Eight.3 Wakesurf Shaper

One of biggest revelations from last year's wake season returns with an improved design and two sizes to better accommodate different boat dimensions. The updated Eight.3 Wakesurf Shaper now features a concave through the center with a more defined leading edge, reducing boat drag, improving fuel efficiency and most importantly - creating a monster swell for you and your crew to session day in, day out.
