Delos ship ?

Scholar Lucien Basch believes that this is the location of the “Delos ship”, which was the flagship of the Macedonian king Antigonus II Gonatas in the naval battle off Cos against Ptolemy II Philadelphus of Egypt, around 250 BC. The largest warships in antiquity were built In this period. This mega-ship, named “Isthmia”, may have had 18 oarsmen per side, on two levels of 9 oarsmen, i.e. 36 oarsmen on a transversal section. With 50 similar sections, a total of 1800 oarsmen would have been on board. The ship would then have to be around 70 m long and possibly 20 m wide.http://www.ancientportsantiques.com/wp-content/uploads/Documents/AUTHORS/AdG/AncientPortsVol-III-Structures.pdf, p. 56.
