The Hull of Yenikapı Shipwreck YK 11: a 7th‐century merchant vessel from Constantinople's Theodosian Harbour

YK 11, a small, heavily repaired merchantman, was one of 37 Byzantine shipwrecks excavated at Yenikap? in Istanbul, Turkey. This 7th‐century hull, abandoned in the harbour as a derelict, was studied by archaeologists from the Institute of Nautical Archaeology. Originally built with mortise‐and‐tenon edge joinery, the ship had undergone a series of significant repairs over its lifetime. Repairs included the replacement of planking as well as framing. Although the repaired vessel exhibits evidence of both shell‐first and skeleton‐first shipbuilding techniques, detailed study of the hull remains indicates that the ship was initially designed and built as a primarily shell‐based vessel.
