小艇.稳定性和浮力评估和分类.第2部分:船体长度大于或等于6m的帆船

[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负载的设计类别（A、B、C 或 D）。 本文件主要适用于船体长度为 6 m 至 24 m（含）的主要由帆驱动的船舶（即使装有辅助发动机）。 然而，它也可以适用于小于 6 m 的船舶，如果它们是可居住的多体船，或者如果它们没有达到 ISO 12217-3 中规定的所需设计类别，并且它们有甲板并具有符合ISO 11812。 关于可居住的多体船，本文件包括对倒转敏感性的评估、可行逃生方式的定义以及倒转漂浮的要求。 本文件不包括： ——ISO 6185 系列涵盖的充气船和刚性充气船，但在 — 吊船和脚踏船中引用的除外； ——冲浪板，包括帆船冲浪板； - 不以排水模式运行时的水翼艇和水翼稳定艇。 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。 [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 load. This document is principally applicable to boats propelled primarily by sail (even if fitted with an auxiliary engine) of 6 m up to and including 24 m hull length. However, it can also be applied to boats less than 6 m if they are habitable multihulls or can be applied 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 ; — gondolas and pedalos; — surfboards including sailing surfboards; and — hydrofoils and foil stabilized boats when not operating in the displacement mode. 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.
