Marine Electrical & Electronics Instructor
Dave created the MECO MET programme from more than two decades of professional marine training and technical experience. The focus is simple: take complex marine electrical and electronics systems and make them understandable, practical and usable in the real world.
The MET 4 follows but also goes beyond ABYC, and ISO Standards, which are limited to small craft up to 24m in length but also - as many technicians discover later - by voltage on the AC side, and by voltage and capacity on the DC side too.
There are an increasing number of well equipped small craft worldwide that fall well outside the remit of ABYC and ISO standards - and technicians have become frustrated with the need for constant re-training in what seems to be a never ending process. MECO addressed this with the MET 4 package.
This package includes all the MET courses you'll ever need - and provides detailed studies in all aspects of the marine electrical, electronics, and high capacity and complex energy storage systems.
more complex advanced battery systems that now require specific formal training and certification. MECO Meets these training requirements and the MET 4 Package is aligned with all the relevant Standards from ABYC, ISO, IEC, NMEA, RCD, IMO and the top 12 Classification societies.
MET 4 · Working with class rules
Classification societies set technical rules for vessel design, construction and ongoing surveys. For marine technicians, understanding class means knowing which requirements apply—and when a proposed installation, repair or change needs review.
The 12 members of the International Association of Classification Societies (IACS).
This describes the rules used for construction. The phrase alone does not prove current class status, or establish what was approved or surveyed. Even if a vessel is not currently in class, changes to its electrical system may affect its insurance risk and should be discussed with the insurer before work begins.
A vessel in class is subject to its society’s continuing requirements and surveys. Class-affecting changes need the appropriate review. Confirm current class status, notations and outstanding conditions with the owner and society before planning work.
MET 4 · Standards in practice
Alongside class rules, marine work draws on standards for electrical installations, lithium batteries and electronics. These organisations have different roles; the right reference depends on the vessel, system and project.
American Boat & Yacht Council
Standards for boat design, construction, repair and maintenance. Learn to connect installation decisions with the relevant requirements for the vessel and work being undertaken.

International Organization for Standardization
Examples include ISO 13297 for AC/DC electrical installations and ISO 23625 for lithium-ion batteries. Practise identifying the scope and applicable edition before using a requirement.
Explore ISO references ↗
National Marine Electronics Association
NMEA 0183, NMEA 2000 and OneNet address marine data interfaces; NMEA 0400 addresses electronics installation. Understand how equipment, cabling and networks fit together.
Explore NMEA references ↗
International Electrotechnical Commission
The IEC 60092 series covers shipboard electrical installations, with Part 507 addressing small vessels. Learn why vessel type and system scope matter when selecting a reference.
Explore IEC references ↗Across the MET 4 package, develop the habit of checking scope, finding the relevant requirement and documenting how it applies. Case studies help you connect electrical and electronics knowledge with the rule-lookup and review process.
