本文件提供了用于技术和商业利益的游艇上与运动相关的舒适度的比较尺度（无判断）。该等级由最多5颗星组成，星的数量越多，船上的舒适度就越高。它允许为特定目的选择最合适的游艇，评估稳定系统的影响，比较设计并确定船上最舒适的位置。 本文件中提出的方法、工作流程和标准可能会有所改进，但未考虑影响船上舒适度的某些重要方面。 本文件未涵盖以下方面:急动、横摇阻尼的推导方法、船尾四分位海、参数横摇的风险、转向装置的影响、绿水和海浪影响、游艇尺寸补偿、性别和年龄依赖性、习惯化。 通过明确列出本文档中未涵盖的方面，读者会意识到这些方面，并可以通过专门考虑改进评估。

This document provides a comparative scale (no judgement) of motion-related comfort onboard yachts to be used for technical and commercial benefit. The scale consists of a maximum number of 5 stars, the higher the amount of stars, the higher the comfort onboard. It allows the selection of the most suitable yacht for a specific purpose, evaluates the impact of stabilization systems, compares designs and identifies the most comfortable position onboard. The methodology, work flow and criteria proposed in this document are subject to possible improvements and do not take into account certain important aspects that influence the comfort onboard. The following aspects are not covered in this document: jerk, the method to derive roll damping, stern quartering seas, risk of parametric roll, the influence of the steering devices, green water and waves impacts, compensation for yacht size, gender and age dependency, habituation. By explicitly listing the aspects that are not covered in this document, the reader becomes aware of them and can improve the assessment with dedicated considerations.
