By using fuzzy theory in ship lines design, a new method is described which produces section area curve and transforms hull form.
将模糊理论应用到船体线型设计中，提出了一种新的横剖面面积曲线生成和线型变换法。

The theory calculations may be divided the following two cases:(1) Appending curve thin ship functions to the waterlines of basis ship respectively, the corresponding improved ship form is calculated.
理论计算可分下列两种情况： （1）对基本船型的水线迭加曲线薄船函数以计算其对应的改良船型。
3
The relationship between probability of failure and sectional modulus of midship is worked out and then drawn as a curve, which can be used in ship design stage.
