What does the Certification look like?

iymcs a6 certif

The custom-designed iymcs booklet type certification is stylish and practical. The booklet outer is made of real leather with a sythentic interior that is resistant to water and protects the certificates. It is A6 in size, ideal to be kept in a crew document case or with the boat's documents in the chart-table.

The iymcs Certificates are printed to ISO9001:2015 standards, are dual-language and feature extensive security features to security level 3 (Government passports & national Iidentification documents are security levels 1 & 2) and can be used as a personal ID in daily situations. (Nb. It cannot be used instead of a passport/national identity card).

Well Proven Benchmark Standards.

The iymcs "Master 200GT/Mate 500GT™" sail is the most comprehensive CoC available at this certification level and has set a benchmark standard that is hard to beat. Supported by STCW ancillary courses and sea-time requirements, it enables a clear path to recognition and approvals by Flag Administrations worldwide. This is an important aspect when you are applying for a job.

The "Master 200GT/Mate 500GT™" sail certificate has two options to choose from, namely: Sailing Yachts and Classic Sailing Vessels. It currently has four types of Endorsements, namely: UnLimited Oceanic, Catamarans, Polar Ice Navigation and light-cargo handling. These Endorsements can be added at any time which is a significant advantage for you as your circumstances may change and you may wish to work on other types of vessels or to operate in other sea areas or oceans.

Certification Options:
i. Sailing Yachts.
(For professional deck crew that are employed on privately registered sailing yachts or on commercially registered charter sailing yachts).
ii. Classic Sailing Vessels.
(For professional deck crew that are employed on classic sailing vessel that engages in a commercial or training activity).
i. Oceanic UnLimited.
(Removes the 150Nm from a safe haven CoC limit for privately registered sailing yachts or for professional crew employed to undertake deliveries of both privately and commercially registered sailing yachts).
ii. Catamarans >17mtrs.
(For professional yacht crew that are employed as a Captain on a charter sailing catamaran).
iii. Polar Ice Navigation.
(For professional deck crew that are working on vessels operating in Polar waters or sea areas of similar characteristics).
iv. Light-Cargo Handling. (For professional deck crew that are working on commercial sailing vessels engaged in carrying light cargo).

The comprehensive subject matter that is covered achieves a good level of depth of knowledge and provides you with a good all-round knowledge base. The course introduces the first of the commercial syllabus such as Safe Working Practises, Risk Assessments, Watch-keeping Requirements, SOLAS etc, etc. This is relatively unique in many of the current offshore yachting certificates currently available (if it is, it is typically lightly mentioned).

For Flag and industry recognitions, as well as for compliance purposes, the ‘Society” has defined clearly the usage and limitations of this CoC which enables it to adhere to the STCW Code. Once again, this is an unusual process for this type of certification but does assist you in a positive way to gain jobs. The ‘Society” has separated the CoC capacities between 150Nm from a Safe Haven for a crew working on privately registered sail vessels and 150Nm from a Safe Haven for a crew working on commercially registered sail vessels for charter.

The CoC is dual-role (often known as polyvalent) and also has a watch-keeping capacity for a vessel up to 500 Gross Tons. It is used extensively to work as a Mate on these size of vessels. The basics functions of Radar, including mini-ARPA and AIS, are incorporated into this course for this reason. The practical course is dynamic and the main intentions of it are to build-up your skill-set so you can professionally run a vessel under the 500GT as a Mate or a sail vessel under 200GT as a Captain.

Other key features to consider:

The diagram below shows how the Endorsements for this CoC work.

After 20 years in development, the iymcs "Master 200GT/Mate 500GT™" sail is well established and is a long-time favourite of professional deck crew.

What is this?

Our Society, the 'International Yacht Marine Certification Society" (iymcs) operates its entire operations under a Quality Management System (QMS) that is in compliance with the International Standards Organisation (ISO) 9001:2015 amended. Part of this compliance involves full auditing procedures.
This is an important reference and enables us to gain recognitions from maritime admininstrations and marine industry bodies alike. The QMS together with the ISO, ensures that iymcs and its Members operate to the highest standards possible. All our courses, and more importantly the Certifications that we issue, are under ISO9001:2015.
This practise is most unusual for such courses and certifications. Some organisations will claim ISO:9001 adherence but often the reality is the ISO compliance is for a very small number of their courses.
