Abstract
The turtle Ship was invented by Lee Sun-shin, Admiral of the Left Naval command of Jeolla Province in 1592. However, no principal dimensions of the turtle ship or the construction profile thereof have been succeeded by the shipbuilders, also no vestiges of or relics related to the turtle ship built in 1592 have been come down to us.

As of today in 2006, those pictures of the turtle ship that illustrated in the history books or the school texts including the model ships exhibited in the government agency are the shape of the turtle Ship built in 1795. This is not the original model of the turtle ship invented by Admiral Lee Sun-shin in 1592. The real shape and structure of the turtle ship built in 1592, which rendered distinguished services having engaged in the naval battle occasioned by Japanese military invasion in 1592, and which was invented 203 years earlier than those that built in 1795, have not been identified and explained clearly yet. For this reason, Korean ancient historical society used to quote the style of the turtle ship built in 1795.

In this research, true and correct historical facts regarding the turtle ship invented in 1592 were pursued and investigated from the perspective of the history in an observable and factual manner, which is also empirically verifiable, having quoted direct historical records along with indirect materials, and at the same time, comparative studies of the sea-going vessel in ancient Korea Dynasty (Goryeo Kingdom) and the traditional sea-going vessel in modern age in-between were conducted.

As to method of research, the principal dimensions, structural data and other resources of the turtle ship, which were recorded in the historical documents and the literatures including Admiral Lee's diary written in the battle field in 1592, the battle reports to the sovereign, the records of 'The Annals of the Choson Dynasty' and other papers relative to the military strategy and operations, were compiled and reviewed, and then treatises and research papers on the topics of the turtle ship worked by the author of this paper that published in 'Bulletin of the Society of Naval Architects of Korea,' etc. were used as references.

From the perspective of the turtle ship building technology, drawing methods of shipbuilding of the traditional sea-going vessel as well as contemporary shipbuilding design techniques were used, and then naval architectural technical materials related to the Korean traditional battle ship had been compiled and applied to the calculations of the principal dimensions of the turtle ship invented by Admiral Lee Sun-shin in 1592.

Based on the results, the lines of hull form(Body plan, Sheer plan, Half-breadth plan) and the construction profile of the turtle ship were drawn. Using the lines of hull form and the off-sets table, the hydrostatic curves were calculated, and displacement, coefficients of hull form, statical stability of the turtle ship built in 1592 and so forth were confirmed and verification procedures were successfully implemented

Table 1 shows principal dimensions of the turtle ship built in 1592. Table 2 exhibits ratio, and Table 3 indicates displacement. Table 4 reveals coefficient of hull form, and statical stability shown in Table 5.
