The four steps involved are illustrated in the Design Spiral ,Ecans(1959) as an interative process working from mission requirements to a detail design, Fig.1.1.这中的四个步骤用Ecans的1959年的设计螺旋循环方式图说明了，设计螺旋循环方式是一种含盖从目标需求到详细设计的迭代过程，如图1.1.Smaller ,less complex vessels may not require every plan listed for adequate definition.小型简单船可能不需要精确定义中所列出的所有的计划。In summary, this chapter considers basic design as that portion of the overall ship design processwhich commences with concept design and carries preliminary design to the point where there is reasonable assurance that the major features have been determined with sufficient dependability to allow the orderly development of contract plans and specifications.简言之，本章将基本设计视为全船设计流程的一部分。该流程从概念设计开始，进行初步设计直到得到合理保证，即能足够可靠地确定主要特征参数以便能够让合同图纸和规范有序的进行。and proceed through rational design engineering with crude assumptions subject to frequent and painstaking revision and development.并通过反复辛苦的修改和完善得出的粗略猜想结合合理的工程设计来继续the absence of contact with small waves combined with flexible seals reduces the effects of wave impact at high speed.船舶高速航行时，弹性密封圈没有与小波浪接触，因而降低了了波浪冲击的影响the example cited above lies between clearcut physically defined categories上述引用的完全是物理意义上分类的例子is similarity to the crude-oil carrier of the preceding discussion goes no further than that它与上述讨论的原油轮有很大的不同。these vessels are most frequently displacement hulls in their larger sizes.这些尺寸更大的船是最常见的排水型船the multihull ship is an adaptation of any of the basic hull categories to a special application that requires exceptional transverse stability and/or the interhull working area.多体船源自于基本船型的改进，有特殊用途，即需要很好的横向稳定性和/或足够的内部工作空间Camber is usually stated as its value on the moulded breadth of the ship.梁拱或说是圆形梁是这样定义的：船舶甲板从舷侧向船中逐渐上升It may be defined either by the angle to the vertical or the distance between the intersection of the stern produced with the base line and the forward perpendicular.倾斜是由相对于垂直面的角度，或船艏与基线的交点离艏柱的距离来定义的。It does not matter where the perpendiculars are, provided that they are precise an
