Course & Certification Structures.

All the CoC's from Master 80GT upwards are solely professional CoC's for professional super-yacht crew or for commercial marine work boat crew depending on endorsements and flag recognitions.
Each CoC has a common base course to it, additional courses are required and endorsements are issued relative to the particular sector and usage by the holder. The professional courses and ancillary courses are in adherence to the STCW 1978 (2010 amend), adhering to MGN requirements under flag recognitions. All the required STCW safety courses for the CoC's are provided by maritime colleges and training centres certified by their relevant administrations.

Maritime Administration Recognitions & Approvals.

We currently have several applications addressed to various Flag Administrations to seek recognition and/or acceptance for a selection of the iymcs Courses, Certifications and CoC's.
Since June 2020, we have been issuing iymcs Certifications of Competency and we have received enquiries from Flag Administrations and Insurance Underwriters regarding iymcs Certificate holders, we have successfully provided support to them and liaised with their requirements. This case-by-case acceptance can be attributed to our work that have undertaken to ensure compliance and adherence to the IMO Conventions, as well as our quality standards of our operations that have been audited and certified by BSI to ISO 9001:2015 Standards: Furthermore, this acceptance has been enhanced by our Society being a European registered, and audited as a professional vocational training Institute, under the CRKBO Registry in the Netherlands.

Area of Activity.

Three main maritime sectors:

Recreational Yachting.

Professional Yachting.

Marine Commercial.

Each sector is considered to be separate for training and certification purposes. There is a clear distinction between recreational yachting courses and professional yachting courses each having a distinct syllabus, assessments, examinations and certificate issuing procedures.



  • The Members (a school or college that runs iymcs courses) are categorised from I to IV.

  • Two of these Member Categories are for professional iymcs courses.

  • Under the iymcs QMS procedures, the Members are unable to run recreational courses and professional courses under the same entity.

  • There are four Member audit levels according to the Member Category level.

  • All Members are actively involved with the Society, and are required to participate in Advisory Panels.

  • Members contribute to course syllabus content and working practices research, and are compensated for their work.

Sea-time Requirements & Verification Practices.

Outline of criteria's:

Certification Revalidation.

All the professional iymcs CoC's and Certifications, and some of the recreational ones, require revalidation every 5 years.
Revalidation consists of one or all of the following: refresher courses, sea-time updated, seaman's medical & STCW Basic Safety courses updated.
