Kos is a fairly large and elongated island of the Dodecanese group, with an area of 290 km2. In antiquity Kos was famous as the birthplace of Hippocrates, the father of medicine. Near the town (about 5 km) there are the substantial ruins of the Aesclepion where the ancient god of medicine Aeslepios, the son of Apollo, was worshipped. The modern town is dominated by the castle built by the Knights of Rhodes after the crusades. There are dangerous shoals N of Cape Kum and the sea can be very confused around the cape.
Also, with a B meltemi there are very violent gusts near the SE shore of the island. Maintain a good distance off-shore.
