Lost Surfboards by Matt 'Mayhem' Biolos, Official Online Store Australia. The Crowd Killer is a high performance, hyper fun board, based off of the Quiver Killer rocker and outline. The idea was to extend it lengthwise and open up this design to a wider audience.It's a wave catching, easy riding machine that does not skimp on performance. The Crowd Killer features: A slightly wider, wave catching nose, with a no flip tip, allowing the added length to still fit into the curve of waves. A wicked little double bump swallow tail, which feels lively and playful in small surf, yet holds long lines in larger waves. A relaxed and fast central rocker, that glides with ease. Plenty of tail rocker, with deep double concave, for whipping wraps like a pro. New 'Hidden Volume two stage deck line, which focuses the foam toward the stringer and a rapid taper towards the rails. This creates a flat, stable deck, without feeling full or bulbous, and allows sensitive yet forgiving rails. Own the local spot, or piss off locals when you travel with this Crowd Killing machine.
