Shop the Slasher Low Pro
Quick answer: The CJ Nelson Slasher Low Pro is a single fin involvement longboard. An involvement board is a traditional style log with more modern rails and bottom, so you can noseride and also make full, drawn out turns without having to work the board for speed.
It suits intermediate longboarders who want one single fin for noseriding and turning, and it works in waves from knee high to about head high. It comes in 9'3", 9'6" and 9'9".

What Is the Slasher Low Pro?
The Slasher Low Pro is a performance single fin longboard designed by CJ Nelson and shaper Ian Chisholm. It moves away from the classic California outline to a semi pig shape, with the wide point set further back.
A pig outline puts more width behind the middle of the board. That gives the board more whip and control in the pocket, the steep part of the wave near the curl.
Who Is the Slasher Low Pro For?
Intermediate longboarders first. You can noseride a bit and want a single fin that also turns well.
Surfers moving up from beginner. The low rocker carries speed and the board is steady when you walk, but the performance rails reward good timing, so it fits best once you are riding the open face.
Experienced loggers and performance surfers. Noseriders who want stronger turns, and performance surfers who want a single fin for smaller days, both fit here.
How Does the Slasher Low Pro Surf?
It noserides well. A concave in the nose and a beveled concave along the bottom give lift and hold when you are up front.
It turns without extra work. Ian told us the tail rocker, heavy concave and refined rails let you wrap full turns without having to work the board for speed.
It keeps its speed. Low rocker helps it carry speed through flat sections, in beach breaks and point breaks from about 1 to 4 feet.
What Sizes Does the Slasher Low Pro Come In?
| Length | Width | Thickness | Volume |
|---|---|---|---|
| 9'3" | 23" | 3" | 69.05 L |
| 9'6" | 23 1/4" | 3 1/8" | 74.34 L |
| 9'9" | 23 1/2" | 3 3/16" | 78.41 L |
Volume, in liters, tells you how much float the board has. Send us your height, weight and current board and we will help you choose a length.
What Fin Should I Use?
Ian told us to use a big fin, around 10.5", in every size. The base and rake of a larger fin add drive, speed and stability, especially on the nose.
Ian told us that works for lighter surfers and for surfers up to about 240 pounds. CJ's Power Flex, Involvement, Noserider, Classic Pivot and Cali Pivot fins all suit it. See our CJ Nelson longboard fins.

How Is the Slasher Low Pro Built?
It comes in Thunderbolt Silver or Thunderbolt Black. These are construction names, not colors.
Thunderbolt Silver is the most traditional feeling Thunderbolt construction. It has carbon fiber stringers inside an EPS foam core and a glass outer shell, so it feels closer to a classic longboard while staying lighter. Thunderbolt Black adds a carbon fiber outer skin and has the quickest spring back.
