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 on the bridge.

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).

The first of the iymcs professional courses, the iymcs Master 80GT24m/Mate 200GT™ power is a versatile CoC and can be adapted for usage through Endorsements. The Endorsements can be added at any time which is a significant advantage for you as your circumstances in the future may change, and you may find yourself working on other types of vessels or to operate in other sea areas or oceans. It also makes it easier to do a cross-over into another certification system of a differing flag administration.

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 60Nm from a Safe Haven for a crew working on commercially registered vessels for charter.

The CoC is dual-role (often known as polyvalent) and also has a watch-keeping capacity for a vessel up to 200 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 motor vessel under the 200GT as a Mate or a motor vessel under 80GT as a Captain.

Other key features to consider:

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

Overall, the iymcs Master 80GT24m/Mate 200GT™ is a great course, it offers a lot and the CoC is versatile.

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.
