Lost Surfboards Crowd Killer

The Crowd Killer is a high performance funboard based on the rocker and outline of the Quiver Killer. With the idea of extending it lengthwise to broaden the audience to less experienced surfers, Lost made a Crowd Killer suitable for a wide range of surfers and waves.

It is an easy board with which you will catch many waves, as it is specially designed for it.


  • A slightly wider nose that catches waves, allowing the extra length to adjust to the curve of the waves.
  • A relaxed and fast center rocker that glides with ease.
  • Lots of rocker in the tail, with deep double concave, for beating wraps like a pro.
  • New two-stage “hidden volume” deck line, which focuses the foam towards the stringer and tapers quickly towards the rails. This creates a flat, stable board without feeling full or bulky, and allows for responsive yet forgiving rails.

Crowd Killer Swallow tail

A mischievous swallowtail, it feels lively and playful in small waves, but holds long lines in bigger waves.

LOST Crowd Killer Round

In contrast to the original Crowd Killer, with a double-wing swallow tail, the Crowd Killer Round tail is more forgiving and easier to turn in better waves and at higher speeds. Less tail area means more control, smoother turns and relaxed riding, with more range in a variety of conditions.

Recommended fins for Crowd Killer Lost Surfboards

For this board model we recommend either of these two sets of fins:

Remember that you can buy your board with any of the two fin systems, choose your favorite!

LOST Quiver Killer vs Lost Crowd Killer

The board model that inspired the Lost Crowd Killer is the Quiver Killer. Here are the main differences between the two models:

The Lost Quiver Killer is an extension of the Short Round model. With so many people enjoying the ShortRound, it quickly became apparent that the short, relatively flat and stubby board was an easy answer for fast fun in smaller waves, but with some limitations.

Quiver Killer

The overall contour and lines of the rocker are a minimalist and simplistic continuous curve. The surface area and volume remain generous enough to create speed on almost any wave. The rounded tail, reduced nose area and extra rocker keep the edge from getting too wet in small waves while still allowing for control and ease of surfing with power and power in the right waves.

Free and easy in small waves, while still being precise and forgiving in solid waves.

Lost says the Quiver Killer is “a direct shot to the heart”.

While Lost Enterprises gained popularity, it was all driven by Biolos’ ability to consistently provide surfers, both world class and novice, with surfboards that outperformed their competition.

Early successes included the Fish Nose Round and the Rocket V3 through to the multi-award winning proformance series the Driver 2.0, surfed by top pros like Kolohe Andino, Grifo Colapinto and Carissa Moore.

In Mayhem’s own words, the key difference between the Lost RNF and most others, from the 90s onwards, is the fact that his scheme was always based more on high performance twin fins, inspired by the competitive-minded MRs of the late 70s and early 80s.
