On January 18, 1947,
Heimara sailed from Thessaloniki bound for
Piraeus with a crew of 86 and about 550 passengers. With the
Greek Civil War in progress, 36 of the passengers were
political prisoners being sent to
exile. Due to adverse weather conditions, her captain decided to set course through the Euboean Gulf and avoid the dangerous
Cape Kafireas (''Cavo D' Oro'') at the southeastern tip of the island of
Euboea. After a stopover in
Chalkida where she disembarked 10 passengers, she put to sea again at 01.30 am. Around 4:00 am of 19 January 1947, while sailing in fog in the
South Euboean Gulf, the vessel hit a reef near the Verdugia () islets, which are located between and . The collision caused
rudder and radio damage as well as flooding. It took
Heimara one and a half hours to sink after the accident, only one mile off the shore of
Kavalliani islet. However, the panic during her disorderly abandonment, combined with the low temperatures and strong sea currents, resulted in around 400 people perishing. Several sources quote 383 victims but the exact figure is unknown as the number of those aboard was not confirmed. ==Aftermath==
