Abstract Hull forms of high-performance sailing dinghies are very interesting for yacht designers. After a long period in which the attention has been focused on one-design boats, in recent years a few exciting restricted classes such as International Moth, International 14′, 18’ Skiff and Class A catamaran become recognized in several countries and led to interesting advances in high-performance yacht design. “1001VELAcup R3” class is two people racing dinghy designed according to a box rule with limitation on LOA and Bmax and total sail area. The boats must be designed and built by students of European Universities and race yearly in Italy. This paper focuses on two best-ranked boats “LED” from the University of Palermo and “TryAgain” managed by the University of Naples but designed by the University of Roma3 team. These boats were definitely superior as regard motion resistance when tested without appendages during 2017 MIDWINTER INDOOR RACE and, although very different in main section shape, had comparable performances. The observed behaviours and the availability of experimental data suggested a suitable numerical approach and a fair comparison between experimental and numerical results is presented.

通过实验和数值评估的帆船水动力阻力

摘要 高性能帆船艇的船体形式对游艇设计师来说非常有趣。在长期以来关注单一设计船之后，近年来一些令人兴奋的限制类如国际飞蛾、国际 14'、18' 小艇和 A 级双体船在多个国家得到认可并引起了人们的兴趣。高性能游艇设计的进步。“1001VELAcup R3”级是根据箱式规则设计的两人赛艇，对LOA和Bmax以及总帆面积有限制。这些船必须由欧洲大学的学生设计和建造，并每年在意大利进行比赛。本文重点介绍了来自巴勒莫大学的两艘排名最高的船“LED”和由那不勒斯大学管理但由罗马大学3团队设计的“TryAgain”。在 2017 年仲冬室内赛期间，这些船在没有附件的情况下进行测试时，在运动阻力方面绝对优越，尽管主要部分形状非常不同，但性能相当。观察到的行为和实验数据的可用性表明了一种合适的数值方法，并提出了实验和数值结果之间的公平比较。
