How It Surfs

With a balanced outline and plenty of foam under your chest, the Quiver Killer is designed to keep you moving—helping you get into waves early, carry speed through softer sections, and maintain control when the face gets steeper. It’s a strong pick for surfers who want a “daily driver” feel, but with enough volume and stability to make sessions more consistent.

Tri vs Quad: Dial In Your Feel

The FCS II tri/quad setup lets you tune the board depending on the conditions:

• Thruster: A more controlled, predictable feel—great for pocket surfing and tighter turns.
• Quad: Added speed and drive down the line—excellent for open faces and generating speed fast.

Fins are not included, so you can choose your preferred fin template and flex to match your stance and local waves.

Great For

• Surfers who want one board to cover a wide range of conditions
• Everyday surf through punchier days when you want extra paddle power
• Intermediate to advanced riders who like thruster control or quad speed
