Lost Surfboards by Matt 'Mayhem' Biolos, Official Online Store Australia. The PARTY CRASHER is a chopped down, volume-up spin off of the popular Crowd Killer, with a nod to the stylish Smooth Operator, but without forgetting the performance and maneuverability of our shorter hybrids like the Puddle Jumper series, thus furthering our adventures into the ego free fun of Mid-length Mayhem. Crash any line up with confidence on this wave catching, yet surprisingly nimble and maneuverable, machine. It excels in lackluster surf, but it can hold in up to size of most surfers comfort level. Its an age appropriate board, that allows more mature surfers to navigate crowded line ups and hit wave quota, without the typical reduction in performance when going with a longer, higher volume board. Meant to be ridden 4-8 inches shorter than a Crowd Killer/Smooth Operator, or 4-8 inches longer than our range of Puddle Jumper styles, short Hybrids, but with similar width and thickness to all.
