Our origins are traced back in 1932 when Nicolaos Apostolou began his marine insurance broking activity with Messrs.Moussouris - Politis Co.Ltd, followed by a number of years with D.S. Svoronos Co. Ltd, till he founded in the early sixties Apostolou – Svoronos Co.Ltd and later Apostolou & Co Ltd Insurance Brokers. Takis Bartsiokas joined the family company in 1977 and established Trireme S.A in 1991 and by maintaining the old ties he expanded significantly the business. Continuing the family legacy Cpt.

Athenean Trireme

The history

Athenian Trireme is rightly desribed as the masterpiece of Ancient Greek ship-building. It was a long, multi-oared warship with auxiliary sails, deriving its name from the three rows of oars which gave Athenians the superiority throughout the Persian Wars and played the leading part in the Naval Battle of Salamis (480 B.C).

According to Greek philosopher Thucydides, the Trireme was introduced to Greece by the Corinthians in the late 7th century B.C by Aminocles of Corinth.

Characteristics: Lenght 40-45m, beam 5 – 5,5m, draft 1,20-1,40. From the lower part of the bow a raw was projected which was the trireme's main weapon. This ship had a total of 170 oars on three levels manned by 170 rowers (54 thalamites, 54 zygioi, 62 thranites. The rowers of the Athenian Triremes were free citizens and not slaves.
