Nice view of a typical cargo Dhow at Jeddah, Saudi Arabia, 1977. Although she was running on an engine when the photo was taken, note the mast and the lowered lateen yard, which qualifies her as a sailing ship. These vessels probably haven't changed much in the past 2,000 years or so.
An Arab Dhow at Jeddah, Saudi Arabia, 1977. Cargo dhows such as this were still a common sight in the Red Sea at that time. The design of these vessels has changed little in the past two thousand years.
