The Barkley is a thruster setup, meaning it has a 3 FCS fin box system.
Every Flatline surfboard is custom crafted to fit the specific dimensions and intentions of its owner. All Flatline surfboards are hand-crafted from an Arctic Foam Core which resists denting and warping while protecting from board discoloration over time. Additionally, each board is reinforced with two Carbon/Kevlar tail strips which protect the toe and heel rails from foot dings. Every board has a 249B Silmar Glass Finish with a 320 UV exhibitor for a slight glossy feel. Finally, all boards have FCS II fin boxes.
