A summary of the finds:
Of the eight ships that the researchers examined for the report, six were classified as "round ships," which means that they were propelled primarily or entirely by sail. The length of the round ships ranged from 26 to 48 feet (8 to 14.7 meters), and they were between 8 and 16 feet (2.5 and 5 m) wide.
The other two ships the researchers examined were galleys — long, oared ships, about 100 feet (30 m) long and 13 feet (4 m) wide. Among all of the 37 shipwrecks discovered at Yenikapi, there were a total of six Byzantine galleys, "notably the first shipwrecks of this type discovered from the Byzantine period," the researchers wrote in their report.
