高速穿浪双体船（WPCat）是一种集合了风浪快速性、耐波性、稳性和运输效率等多方面优势的新船型，适合在高海况的海域航行，具有良好的航向性能和经济性能。其片体线型是影响其阻力性能和耐波性能的一个重要因素。为了探索最优的片体形式，设计了不对称型、深 V 型、圆舭型、深 V 球艏型和圆舭球艏型五种不同形式的片体，在等排水量、同主尺度及船型系数相近的前提下，应用Hullspeed和Seakeeper程序对WPCat选用不同片体方案时的静水阻力和耐波性进行了计算。计算结果从静水阻力、波浪增阻及横摇、纵摇和垂荡3种运动响应等角度进行综合分析比较，结果显示选用深V型片体综合优势明显。这一结论为WPCat船型的片体设计与选择提供参考。

The high-speed Wave Piercing Catamaran (WPCat) is a new type of ship having multiple advantages in terms of rapidity in waves and seakeeping, stability and transportation efficiency. It has good navigation and economic performance and suitable for sailing in rough weather conditions. The demihulls is an important factor affecting the resistance and seakeeping performance. In order to explore the optimal type of demihull, five kinds of demihull are designed, i.e., asymmetric, deep V, rounded bilge, deep V bulb bow and rounded bilge bulb bow under the premise of same displacement, main dimensions and hull-form coefficients. Hullspeed and Seakeeper software are used to calculate the calm water resistance and seakeeping performance of each design. The calculation results are analyzed and compared in a comprehensive way according to the calm water resistance, wave added resistance, roll, pitch, and heave motions. The conclusion is that deep V demihulls have obvious overall advantages. This study can provide some reference for the demihull design and selection of WPCat ship type.
