Maintennace Services Discription

At YSM, we understand the importance of regular vessel maintenance in enhancing the safety and dependability of your asset. Our team of experts leverages the latest industry standards and regulations to provide comprehensive maintenance services tailored to your unique needs and requirements. Whether you need to comply with manufacturer guidelines or regulatory requirements, our team is here to help you. With the flexibility to schedule maintenance at your convenience, you can enjoy peace of mind knowing that your vessel is in top condition.


At YSM, we offer a comprehensive Mechanical Maintenance Inspection (MMI) service tailored to your vessel. Our expert team performs a thorough initial inspection, including extensive photographing and documentation, to provide a clear view of the health of your vessel. The result is a baseline maintenance file that serves as a valuable tool for ensuring the longevity and reliability of your asset.

Benefits of our MMI service include:

  • Custom-built Inspection checklist specific to your vessel's systems.

  • Thorough inspection with extensive photography and detailed report.

  • Peace of mind through a clear understanding of the health of your vessel.

  • Option to provide the report to insurance carriers and brokers to obtain better rates and resale value.

  • Comprehensive inspection that goes beyond the average survey, ideal for clients looking to buy a vessel.


Our rates are calculated per foot, and we're proud to provide our clients with a peace of mind through a comprehensive and reliable MMI service. See below an example of an MMI for a 75 Sunseeker.
