To date, we have carried out pre-purchase surveys for more than 700 sailing and motor yachts both in Turkey and abroad. In addition, we have successfully supervised quality control and inspection processes for sailing and motor yachts ranging from 33 to 126 feet in length.

During my 14 years of experience at Sirena Marine, I took an active role in the quality control and final approval stages of 342 yacht production processes.

To date, I have conducted surveys on 43 different yacht brands, building an extensive technical archive of approximately 165,000 photographs and inspection records.
Throughout these surveys, I have identified and documented around 16,000 findings, including issues related to osmosis, structural damage, and previous fire incidents.

We conduct comprehensive on-land and at-sea surveys for all types of sailing and motor yachts both in Turkey and abroad. Following detailed inspections and technical evaluations, we prepare officially recognized survey reports in compliance with international standards.

As a member of the American Yacht and Boat Council (ABYC), our reports are internationally acknowledged and professionally accredited.
During each survey, our priority is not only to assess the vessel’s current condition, but also to adopt a proactive approach, identifying and reporting any potential risks or components that may cause future malfunctions.

Following each survey, we conduct a comprehensive analysis of potential issues, providing clients with accurate guidance on maintenance, technical services, and qualified repair facilities.
Our primary goal is not only to assess the current condition of the vessel, but also to prevent potential hazards and critical risks that may occur at sea.

During surveys, we employ a wide range of advanced electronic and mechanical diagnostic instruments.
All calibration-dependent devices are maintained with up-to-date calibration certificates to ensure precision and reliability in every inspection.

We are fully equipped to perform detailed inspections on fiberglass, steel, aluminum, and wooden yachts, utilizing specialized instruments suitable for each hull type.
