The design methods for many vessels during the Restoration period (1660–88) are only partially understood. Charles II’s 23 yachts represent the pinnacle of design and construction for small, fast vessels of this era but there are no extant design treatises or draughts relating to any of them. The only primary archaeological data comes from contemporary models. One such model, in the collection of the National Maritime Museum in Greenwich catalogued as SLR0375 circa 1680, is a particularly fine example. With the aid of modern scanning techniques supported by extensive background research, it has been possible to suggest the design method employed by Sir Phineas Pett in shaping the hull and the possible reasoning behind it. Reference to Pett and his yachts, along with a ‘hanging-conoid’ method of design, is described in some detail by William Sutherland in his eighteenth-century shipbuilding treatises. Sutherland’s ideas and observations have helped to unlock secrets relating to the design of the yacht, which represents a major step forward in the understanding of the design of these vessels.

在恢复期（1660–88）期间，许多船只的设计方法仅得到部分了解。查尔斯二世的23艘游艇代表了该时代小型快速船的设计和建造的顶峰，但是没有任何相关的现存设计论着或草稿。唯一的主要考古数据来自当代模型。一个这样的模型就是一个很好的例子，该模型在格林威治的国家海事博物馆（收藏于1680年左右）中被编录为SLR0375。借助于广泛背景研究支持的现代扫描技术，有可能提出菲尼亚斯·皮特爵士在塑造船体时采用的设计方法及其背后的可能原因。参考Pett和他的游艇，以及“悬挂圆锥形”的设计方法，威廉·萨瑟兰（William Sutherland）在其18世纪的造船专着中对其进行了详细描述。Sutherland的想法和观察帮助揭开了与游艇设计有关的秘密，这代表着对这些船只设计的理解迈出了重要的一步。
