Coefficients of Form – Ship’s Waterplane, Block, Midship and …
Waterplane Area Coefficient (Cw) It is the ratio of the actual area of the waterplane to the product of the length and breadth of the ship. As seen below, the area of the ship’s waterplane is shown shaded and a rectangle having the same length and breadth of the ship: Coefficient of fineness (Cw) = Area of waterplane ÷ (Length x Breadth)

小水线面双体船 (Small Waterplane Area Twin Hull，SWATH)是由水下左右两个潜体、宽敞的上船体和连接水下潜体的支柱三部分组成。其原理是将提供船舶大部分浮力的浮体置于远离波浪干扰的一定水深处，水线处只有截面很小的支柱，减小了水线面面积，而上船体距离 ...
Form Coefficients of Ship – Block, Midship, Waterplane and …
2023年2月25日 · The waterplane area coefficient shows how similar is the ship’s waterplane to a rectangular block of the same length and beam at a particular draft. The more a waterplane resembles a rectangle, the higher is its waterplane coefficient.
The Engineering Handbook - Ship Form Coefficients
The waterplane area is determined by integrating y(x,z) from the aft part of the waterline x a to the forward part x f. The integral below is valid for symmetrical hulls with x being the axis of symmetry i.e. normal hull shapes.
水线面面积曲线 - 百度百科
水线面面积曲线简称Aw曲线，是指船舶与水接触的轮廓线构成的平面面积随着船舶吃水变化的坐标曲线，通常表示船舶水线面面积随平均型吃水增加而增加的规律，可以反映船舶的浮性和稳性等船舶特性。 [2] 在任意吃水下，水线面面积曲线与纵坐标轴所包围的面积为在此吃水下的排水体积。 此面积除以水线面面积与吃水的乘积为船在此吃水下船体的垂向棱形系数。 面积形心的垂向坐标即为浮心的垂向坐标。 [1] 水线面面积曲线如图1所示，它反映了船舶排水体积沿吃水方向的分 …
For example water plane areas, block coefficients, TPC, MCTC, KB and LCB of such objects can be found using simple formulae. We can easily obtain the particulars at any draught and if necessary plot the curves. However not all ships have simple and uniform shapes as above. In fact, most ships have hull shapes which are varying in three directions.

Water Plane Area and Block Coefficient
The waterplane area of a ship is the area of the hull at the draft where the ship floats. It is used to calculate the ship's displacement and longitudinal center of flotation at different drafts. The waterplane area is calculated using Simpson's rules, which provides the area for non-symmetrical ship shapes by using half-ordinate values and ...
船舶水线面系数 - 百度文库
船舶水线面系数（coefficient of waterplane area，CWP）是指船舶水线面积与长乘宽的比值，表示船舶水线形状的圆润程度，也称为船型的宽度系数。 水线面积是指船舶水线与船底之间的面积，长指船体的水线长，宽指船Baidu Nhomakorabea最大宽度。
