The shallow-draft high-speed catamaran comprises a catamaran body, the catamaran body comprises two sheet bodies, and the two sheet bodies are connected through a connecting bridge; the sheet body comprises a wave piercing prow, a round bilge ship middle and a square stern which are in smooth transition connection in sequence; the bottom surface of the wave piercing prow is in a deep V line shape, and the front end of the wave piercing prow comprises a pointed upper prow and a pointed lower prow; the area of the cross section of the wave piercing prow is gradually increased from front to back; the left side and the right side of the front portion of the sheet body are provided with inwards-concave half-small waterplane linear surfaces, and the inwards-concave depth is gradually reduced from front to back. The semi-small waterline surface linear surface is positioned at the designed waterline height of the ship body; according to the design, routes of different navigation areas such as a coastal shoal, a coastal navigation area and an offshore navigation area can be considered at the same time, it can be guaranteed that propellers do not make contact with the bottom under the condition that the water depth is 2 m at the low tide level, navigation safety under the shallow draught working condition is guaranteed, rapidity is guaranteed, and meanwhile the seakeeping performance, the seaworthiness and the passenger comfort of the ship are improved.
本申请涉及一种浅吃水高速双体船,包括船体,船体包括两个片体,两个片体之间经连接桥相连接;片体包括依次平滑过渡连接的穿浪船首、圆舭船中、方形船尾;穿浪船首的底面为深V线型,穿浪船首的前端包括尖形的上船首、下船首;穿浪船首的横截面面积由前至后逐渐增大;片体前部左右两侧设置有内凹的半小水线面线型面,内凹的深度由前至后逐渐减小;半小水线面线型面位于船体的设计水线高度处;本设计能同时兼顾近岸浅滩、沿海和近海航区等不同航区的航线,在低潮位时水深2米情况下可保证螺旋桨不触底,确保浅吃水工况的航行安全,保证快速性的同时,提高船舶的耐波性、适航性和乘员舒适性。
