What does the Certification look like?

iymcs a5 certif

The custom-designed Iymcs presentation folder type certification is stylish and practical. The presentation folder outer is made of real leather with a sythentic interior that is resistant to water and protects the certificates. It is A5 in size, it can hold up to four Certificates, and is an ideal size to be kept in a crew document case or with the boat's documents.

The Iymcs Certificates are printed to ISO 9001:2015 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 Radar Navigation (O) course is the IMO model course ref. 1.07, concerns the operation of Radar for watch-keeping at an operational level for Master of vessels less than 500GT, Officer of the Watch of vessels less than 1600GT, carrying no more than 12 passengers.

The course focuses upon collision avoidance between vessels, near-coastal navigation and close-quarters pilotage: It is most suitable for deck/bridge watch-keepers on super-yachts, classic sail vessels and small commercial workboats.

An IMO type approved 2-station (instructor+student) consisting of Radar, ECDIS with visual scenario reality, is used. This enables you to practice the coordination the operation of radar together with ECDIS, as well as visually what you are seeing in the scenario. The scenarios are created by the instructor using worldwide ports, harbours, narrow channels of all types and sizes with varying coastal features. The sea & meteorogical conditions are varied, vessel traffic is increased/decreased using different types of vessels.

A continous assessment is made of how you perform the tasks on the simulator, which is graded according to the operation standard you have achieved. Additionally, there is a written Radar Navigation Theory & Plot Exam to undertake and pass to qualify.


Certification Structure:
The certification issued is an Iymcs Certificate of Proficiency (CoP), it needs to be presented to the Flag Administration of the vessel you intend to work-on, or are working on, for their independent assessment, acceptance on a case-by-case basis.

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 administrations 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 ISO 9001:2015.
This practice is most unusual to see for such courses and certifications. It ensures a uniform and consistent quality standard throughout the Society's operations.
