小艇 稳定性和浮性的评定与分类 第1部分:艇长长度不小于6米的非帆艇

[中文适用范围]： 本文件规定了评估完整（即未损坏）船只的稳定性和浮力的方法。 还包括易受沼泽影响的船只的漂浮特性。 使用本文件对稳定性和浮力特性进行评估将使船舶能够被分配到适合其设计和最大总负载的设计类别（A、B、C 或 D）。 本文件主要适用于由人力或机械动力推进的船体长度为 6 m 至 24 m 的船舶。 然而，如果船长未达到 ISO 12217-3 中规定的所需设计类别，并且其有甲板并具有符合 ISO 11812 的快速排水凹槽，则它也可以适用于 6 m 以下的船舶。 对于可居住的多体船，该文件包括对翻转敏感性的评估、可行逃生方式的定义以及翻转漂浮的要求。 本文件不包括： ——ISO 6185 系列涵盖的充气船和刚性充气船，但参考文献除外 — ISO 13590 涵盖的个人船只和其他类似动力艇； ——贡多拉和脚踏船； ——帆船冲浪板； ——冲浪板，包括动力冲浪板； ——不以排水量模式运行时的水翼船和气垫船；和——潜水器。 注：位移模式意味着船仅由静水力支撑。 它不包括或评估拖曳、捕鱼、疏浚或起重作业对稳定性的影响，如果合适，需要单独考虑。 1 [外文原描述]： This document specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of boats susceptible to swamping are also encompassed. The evaluation of stability and buoyancy properties using this document will enable the boat to be assigned to a design category (A, B, C or D) appropriate to its design and maximum total load. This document is principally applicable to boats propelled by human or mechanical power of 6 m up to 24 m hull length. However, it can also be applied to boats of under 6 m if they do not attain the desired design category specified in ISO 12217 ‑ 3 and they are decked and have quick-draining recesses which comply with ISO 11812 . In relation to habitable multihulls, this document includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation. This document excludes: — inflatable and rigid-inflatable boats covered by the ISO 6185 series , except for references made in the ISO 6185 series to specific clauses of the ISO 12217 series ; — personal watercraft covered by ISO 13590 and other similar powered craft; — gondolas and pedalos; — sailing surfboards; — surfboards, including powered surfboards; — hydrofoils and hovercraft when not operating in the displacement mode; and — submersibles. NOTE Displacement mode means that the boat is only supported by hydrostatic forces. It does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which need to be separately considered if appropriate.
