Affected Passengers and What to Do
This cancellation primarily concerns passengers who had chosen the 16:00 service to return to Bostancı or Yenikapı from Avşa and Marmara Island. Passengers whose travel plans are affected should consider alternative transportation options or obtain updated information from İDO's official channels.
The announcement emphasizes that only this specific service on the mentioned date and time has been canceled. Passengers traveling on the same day at different times or on different routes (e.g., Avşa - Erdek or Avşa - Tekirdağ) are advised to check the status of their respective services separately.

Ferry Services and Weather Conditions in the Sea of Marmara
The Sea of Marmara can experience variable weather conditions, especially during autumn and winter months. Conditions such as strong winds, storms, or dense fog can prevent sea bus and ferry services from operating safely. In such situations, cancellations or delays are common to ensure passenger safety. Maritime companies like İDO make these decisions based on data received from the General Directorate of Meteorology and their own operational assessments.
