Abstract

The ancient sailing routes between Silla Korea and Tang China have been a hot issue among the researchers. Some assert that the Korean seafarers under Chang Po-go sailed the East China Sea directly from China to the Korean Peninsula with the assistance of mariner's compass on boarding V-shaped vessels in the 9th century. As we all know, Chinese used the mariner's compass in the 11th century and Europeans in the 12th century. In this paper, the author analyzed the maritime meteorological condition for sailing ships to navigate in the East China Sea and retraced the rafting route by Yun in 1997. As the results of analysis, the author confirmed that the maritime meteorological condition might be favorable for the seafarers to be capable of navigating in the East China Sea from China to Korea in June and July. But even the sea condition might be favorable, it must be God's will for the ancient seafarers to reach the Korean Peninsula. On Yun's rafting account, the author found out that there is a difference between the sailing route drawn by Yun himself and the actual drifted route and the raft drifted at 1.7~2.0 knots. This was quite an extraordinary speed considering the unfavorable sea condition and raft itself without keel. In conclusion, the author reaffirms that it was after the year 1068 for the seafarers to navigate in the East China Sea directly from China to Korea without any historical proofs or evidences.

최근 일부 연구자들은 9세기 장보고 휘하의 신라인들이 항해에 나침반과 첨저선을 이용하여 동북아 해역을 자유롭게 항해하였다고 주장하고 있다. 그러나 항해에 나침반이 이용된 것은 중국이 11세기이고, 유럽이 12세기이다. 게다가 우리 선조들은 평저선을 사용하였다는 것이 학계의 중론이다. 이 논문은 중국 주산군도에서 흑산도를 잇는 동중국해 사단항로(서해남부 사단항로)의 이용 시점에 관하여 해양기상학적 관점에서 재검토해 보려는 시도이다. 이를 위해 고대 동중국해 사단항로에 관한 이제까지의 연구성과를 정리한 뒤, 동중국해의 해황(海況)을 바람과 해류, 안개를 중심으로 살펴보고, 뗏목으로 동중국해를 항해함으로써 장보고 선단이 동중국해 사단항로를 이용하였음을 입증하였다는 주장을 비판적으로 재구성해 보았다. 분석 결과 6 7월 해황은 동중국해 사단항로의 범주 항해가 가능함을 보여주고 있지만, 그것도 기상 조건이 아주 유리했을 경우에 한하여 한정적으로 가능했음을 확인하였다. 뗏목 탐사의 경우 제시된 항로도와 실제 선위간 이동경로와는 다소 상이하였고, 속력 또한 1.7 2노트 내외로 빠르게, 그것도 직선에 가깝게 이동한 것으로 분석되어 아주 이례적이었음을 확인하였다. 결론적으로 명확한 사료와 확실한 근거가 없는 한 동중국해 사단항로는 1068년 이후 주항로로 이용되었다는 설이 견지되어야함을 재확인하였다.
