What does the Certification look like?

iymcs a7 certif

The custom-designed iymcs wallet type certification is stylish and practical. The wallet outer is made of real leather with a sythentic interior that is resistant to water and protects the certificates. It is wallet size, comfortable to carry around, it is not too small to lose like the credit-card style type certifications you often see now.

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 DeckCrew™ Course is a multi-purpose versatile training course aimed at crew of sailing yachts & classic sail vessels who wish to either build or enhance their practical skills and knowledge. The course is offered in four formats shown below, each is configured to a particular level of experience:

Course Format


Beginner Novice
(No Experience).

Ideal for persons looking to gain a basic general knowledge of sailing, develop their personal skills to the level they feel confident with.

Experienced Crew
(Ocean Cruising).

Focusing upon the working practices found on-board the larger explorer and ocean cruising yachts >16 mtrs, topics include; safety procedures, safe working practices, watch-keeping, maintenance and repair skills. Essentially building seamanship skills from their existing knowledge and experience.

Classic Sail Vessel Crew
(Limited Experience).

A hands-on learning forum for crew to actively participate with on-board tasks that include traditional seamanship, navigation techniques, rope & canvas work and the maintenance work of classic sail vessels.

(Limited Experience).

For the Skippers that would like to fill-in missing gaps of knowledge and be coached 1-to-1 upon particular tasks such as boat handling, general seamanship, maintenance and repairs, radio GMDSS communications, pilotage, passage planning, navigation.

Confidence building is a fundamental part of this training. A unique aspect of the Course is the iymcs Task Book which features standard tasks which you undertake, the tasks are set according to the format chosen for the Course. There is also the option to add particular task/s that you would like to practise under the guidance of your Instructor.

The teaching of these tasks is not just from a single-minded approach ie. this is the way it should be done. The Course offers wherever possible, alternative methods for doing a task, the principal role of your Instructor is to advise you of these differing methods as well as to identify which of the method/s work best for you.

A successful outcome to the iymcs DeckCrew™ Course is whereby you have achieved your personal objectives and you have reached a level of competency as deck crew that you are satisfied with. This outcome is very much reflected in the Certification itself.

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.


How much does the course cost?

The following are the recommended iymcs course prices (ex.VAT), prices may fluctuate between Member schools & colleges.

Scandinavia 800,-EUR Northern Europe 700,-EUR United Kingdom 800,-GBP
