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).

The iymcs "Master 40GT/17m™" power is a unique course and certification that has the capacity to cross-over from a non-commercial status to a commercial status in such a way that it respects the STCW 1978/2010 convention. There are no other CoC's for yachts and small commercial vessels that do this except possibly for a national Certification issued by a few Maritime Authorities. If this commercial option is chosen, it will allow crew of motor yachts and commercial vessels of under 40GT/17mtrs to work as a Captain in near-coastal waters subject to the approval by; the owner, the insurance company, the flag of the vessel and the regional Coastguard.

The cross-over from non-commercial to commercial can be done at any time, this is ideal for yacht owners that may consider to do owner-operator charters themselves as a Captain. For "professional deck crew" from the smaller commercial workboats, the iymcs "Master 40GT/17m™" power CoC is a good alternative to the often long studies at maritime college for higher level CoC's. This Commercial CoC option can be used, subject to the approvals mentioned above, for working as a Captain on the smaller <17mtrs boats such as dive-boats, crew transfer vessels and workboats.

There some other smart features of this course.

The diagram below shows the commercial and non-commercial qualfiying aspects of this CoC.

The unique format of the iymcs "Master 40GT/17m™" power is progressive and allows you to develop your skill set at your own learning pace. Within the extensive syllabus, you can choose several course subjects that you wish to focus upon. Another unique feature of the course is the up-to-date learning techniques that begin with the use of technologies to understand subjects and techniques, these are then underpinned by the practise of traditional methods and values as the course progresses. This approach is avant-garde and is very effective in getting to the point of what you need to know, as well as which skills are needed, to safely navigate. On-board training in elementary Radar is included that covers thr basic operations, there is a maritime law module which covers the essesntial fundamentals required in near-coastal waters.

As with all the iymcs courses, safety is a key element but iymcs takes the subject a stage further. To understand safety, an important criteria is situation awareness. The iymcs "Master 20GT/17m™" power course focuses upon situation awareness skills that are vital in near-coastal waters, and deals with likely scenarios and the options on how to deal with them.

The iymcs "Master 40GT/17m™" power course course and CoC is smart, it is proactive and has the possibility to change and develop as required. It is the bridge between the recreational world and the professional world, a competent all-rounder that opens future possibilities.

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.
