Introduction to V-shaped profile
The V-shaped profile often matches the convex design waterline. Its small wet surface area can reduce friction resistance; the water flow is easy to flow toward the bottom of the ship, and can avoid the generation of vortex in the bilge. The V-shaped profile is generally used at the bow end of a low-speed ship, which can reduce pitch and heave, which is beneficial to improve the splashability, and is easier to maintain speed than the U-shaped profile in wind and waves. When the V-shaped profile is used at the stern of a twin-screw ship, it is convenient to arrange the stern frame. The V-shaped profile ship raises the buoyancy center and the center of gravity, which is favorable for stability and wave resistance with the large waterline, but the narrow bottom is unfavorable for the arrangement of the cargo cabin and the engine room. , Lane recognition becomes unreliable, which greatly reduces the distance of lane recognition.
