Lost 6'4" Cobra Killer Surfboard

The Lost 6'4" Cobra Killer is a post-modern twin-fin surfboard, born from a special collaboration between shaper Matt Biolos and Paul Lefevre, known as "Son of Cobra." This design merges Lefevre's unique, deep double concave bottom contours with the proven outline, foil, rails, and rocker of the Quiver Killer model, resulting in a board that offers exceptional speed, drive, and maneuverability.

Stock Dimensions

  • Length: 6'4"
  • Width: 21.50"
  • Thickness: 2.75"
  • Volume: 41 liters

Key Features

  • Deep Double Concave Bottom: Enhances speed and drive, providing a lively and responsive feel underfoot.
  • Relatively Pulled-In Rounded Pin Tail: Offers improved control and maneuverability, allowing for sharp, responsive turns.
  • Twin Fin Setup: Built exclusively as a twin-fin, eliminating the need for a trailer fin due to the deep concave and tail design.
  • Unique Aesthetics: Features dual dark wood stringers, embossed metal glassed-in labels, and minimalistic Lost x Cobra logos, complemented by pastel resin tints with fin and tail patches.

Performance Overview

The Cobra Killer is designed to be exceptionally fast, providing substantial drive while maintaining control. The deep double concave bottom works in harmony with the pulled-in tail to allow for sharp, responsive turns without the looseness often associated with twin-fin setups. This design makes the board suitable for a variety of wave conditions, offering a balance between speed and maneuverability.

Why Choose the Cobra Killer?

The Lost 6'4" Cobra Killer Surfboard is ideal for surfers seeking a blend of classic twin-fin speed with modern control and responsiveness. Its unique design elements and collaborative craftsmanship make it a standout choice for those looking to expand their quiver with a versatile and aesthetically distinctive board.
