Re-Estimating the Size of Javanese Jong Ship

Abstract

It is known that the Javanese jong ship is larger than Portuguese ships. There have been several scholars who have estimated the size of the jong ship, though in an unspecified manner. This study is intended to estimate the size of the jong ship by calculation. This paper explores historical records of jong sizes, claims of jong sizes, and calculates jong sizes with formulas according to shipbuilding rules. From the calculations carried out, the size of the Javanese jong is obtained. The results of this calculation reject and confirm the jong size research that has been done by other scholars, the claim that the jong can reach more than 300 m is rejected by the results of the calculations that have been carried out.
