Image of Korean ship during the Koryo (or Goryeo) era

In the book Tree-ear left Ch'ulp'o and took a journey to Songdo (now known as Kaesong) by boat. I thought it would be interesting to see what the boats looked like during the Koryo (or Goryeo) era (A.D. 918-1392)



The image on the left is a "China junk" boat that was used from 220AD on. Although this is a Chinese boat design, it was used throughout Asia. This particular image is from the 13th century. (Image from http://www.newworldencyclopedia.org/entry/Junk_%28ship%29)

A historian named H. Warington Smith said,

"As an engine for carrying man and his commerce upon the high and stormy seas as well as on the vast inland waterways, it is doubtful if any class of vessel is more suited or better adapted to its purpose than the Chinese junk, and it is certain that for flatness of sail and handiness, the Chinese rig is unsurpassed."

The "panokseon" boat show below originated a little bit after the book takes place (originated in the 16th century) but still will give an idea of what a Korean oar and sail-propelled ship looked like. The vessel "served as the main class of warship used by the Korean Joseon Dynasty during the late sixteenth century."
