10:27 a.m., Qingdao Smuggling Crime Investigation Bureau Pier.
Two brand-new, modern anti-smuggling boats were docked on the inner and outer sides of a dunship at the anti-smuggling dock. The vessels were sleek, streamlining from bow to stern, significantly reducing water resistance compared to the typical deep V-shaped boats.
After six consecutive days of trial sailing, it could be felt that at medium and low speeds, the boat's bottom generated significant dynamic lift, with resistance comparable to the round-bilge type boats previously equipped in Qingdao.
Due to features like a full-length chine line, V-shaped transverse section, and smaller waterline entry angle, along with a large transverse deadrise angle at the stern and appendage designs such as long tail fins and bilge keels, its wave resistance performance was excellent.
