Do you know dear visitor that Al-Boom -ship has five Sails (shira'a). The two bigger Sails are Al-Oud and Al-Qalami. The other three are Al-Boomiah -small Shira'a on the front and Shamandi- on the back -tofar. Qabiah is another Sail located on top of Al-Oud, and there are other Sails for special kind of weather conditions, like "Terkate" and  "Sefdairah". Each one of these Sails has its own purpose.
