Turtle Ship - Tank of the Sea
Korea's shipbuilding technology has greatly developed over time. Moreover, iron rods strengthened the structure of the ships while charging tactics became quite common during battles. The Turtle Ship is a newly created sea tank originated from spear ships and firearms and wood board covered warship. The main measurements and combat strength of the Turtle ship as the right table.
Dragon head Length of Dragon head 1.3m
Body Length of body 21.5m
Width of upper deck 9.2m
Length of lower deck 15.3m
Combat Strength Passengers Combat soldiers 45
Number of oars 16
The traditional naval battles have been mainly fought by jumping onto and capturing enemy ships, however since the Turtle Ship is entirely covered with planks and sharp spears, the opposing enemy could not jump aboard. The Turtle Ship is built by sturdy red pine trees with a thickness of 12 cm.
The specific gravity of the red pine trees is 0.73 which is greater than the average lumber (0.41-0.47) commonly used in ship building. Moreover, the ship has been constructed with water swelling wooden pegs permitting stronger structure in water. With these advantages the Turtle Ship is able to use charging tactics to crash and sink enemy warships.
Mobility-The oars are located in the inner side of the upper deck (figure).If the oars are located outside of the side-wall, they are likely to be damaged during crash into an opposing ship, However since the oars are located inside, the oarsmen can continue rowing regardless of crashes during battles.
