The Yarabuoki underwater site contains seven iron grapnel anchors and Early Modern Okinawan ceramic jars and is dated to the 16th–19th centuries. The site lies at a depth of 12–32 m off the western coast of Ishigaki Island in Okinawa, Japan. Based on underwater archaeological and broadband multibeam surveys, as well as historical research of the artefacts and Early Modern Ryukyuan shipping, we discuss the possible anchor and vessel types in Ryukyu and Eastern Asia in Early Modern times. We also discuss the efficacy of low-cost ROV for assisting surveys in shallow-water environments and the value of educational programmes for promoting the management and conservation of underwater cultural heritage.

近代琉球铁钩锚的发现与日本冲绳的水下文化遗产管理

Yarabuoki水下遗址包含七个铁gra锚和早期的冲绳早期陶瓷罐，其历史可追溯至16至19世纪。该场地位于日本冲绳石垣岛西海岸外12–32 m的深度。基于水下考古和宽带多波束调查，以及对文物和近代琉球早期航运的历史研究，我们讨论了近代琉球和东亚可能存在的锚和船只类型。我们还将讨论低成本ROV在浅水环境中协助调查的功效以及教育计划对促进水下文化遗产的管理和保护的价值。
