The DHD Wilko F13 is described as a "little rocket" that excels in a variety of conditions, particularly weaker ones, by generating speed effectively. Its design features a 13-inch nose, good width up front, and a relatively flat deck which contributes to paddle power and foam carry under the chest. This flat deck also allows for nicely foiled rails that engage well during turns, making the board maneuverable and sensitive. The rocker profile consists of a flat entry rocker for speed generation and lift in the tail for increased maneuverability and rail engagement in steeper conditions. The bottom contour features a single concave running through the board that transitions to a double concave in the tail, designed to channel water for drive and acceleration through turns. The Wilko F13 is recommended for surfers looking for a high-performance shortboard that can handle smaller, sloppier waves and even punchy conditions. It's considered a versatile option that doesn't sacrifice performance for paddle ability. The review suggests pairing it with FCS Performer fins. The fin setup appears to be a thruster configuration with nicely foiled rails and a refined tail.
