The complete picture.

From electrical basics to electronics.

Leisure sailors & boat owners

Understand how your onboard electronics work together.

Commercial skippers & crew

Build knowledge of navigation, communications and data systems.

Marine technicians & trainees

Progress from electrical foundations into electronics and network diagnostics.

What's included

Build your skills from beginner to advanced with one training package. Including: fault finding, inspection, installation and maintenance of Marine Electrical and Electronics systems on Small craft, yachts, and commercial vessels up to 50m. Package includes MET 1, 2 & 3.

One package for life

For anyone new to the topic learning within 4 different standards based on systems, vessel sizes, and countries can lead to repetitive training courses from multiple providers, and a few years later you need to renew everything all over agin! MECO has addressed both these issues with a comprehensive one-stop solution with lifetime access. This saves our trainees time, effort and money.



With the MET 3 Master Pro - Boat & Yacht Electronics training package you start with the fundamentals of electricity within the MET 1 and 2 level - and build from these basics step by step. Before you know it you'll have a highly detailed knowledge of marine electronics systems.

The MET 3 module dives into every tiny detail about how marine electronics source, convert and distribute information via the vast array of marine data networks - including the most detailed study of NMEA 2000 available online today.

Ideal for trainee marine electricians, engineers, boat owners, and yacht crew of vessels from 5m to 50m.

MET 3 · Standards in practice

Know which standard to turn to.

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.

ABYC

American Boat & Yacht Council

Boat electrical systems

Standards for boat design, construction, repair and maintenance. Learn to connect installation decisions with the relevant requirements for the vessel and work being undertaken.

Explore ABYC references ↗

ISO

International Organization for Standardization

Small-craft electrical & lithium systems

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 ↗

NMEA

National Marine Electronics Association

Marine electronics & data networks

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 ↗

IEC

International Electrotechnical Commission

Electrical installations on vessels

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 ↗
Connect the requirement to the real job.

Across the MET 3 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 process of finding and applying relevant standards.

THE COMPLETE MET 3 MASTER PRO PROGRAMME

Three levels. One complete learning pathway.

Start with electrical fundamentals, progress into more complex marine electrical systems, then explore marine electronics and connected networks. MET 1, MET 2 and MET 3 are all included.

LEVEL 01 · MET 1

Foundation

Included in your package

Start from the basics of how electricity behaves in a circuit, then apply that knowledge to onboard electrical systems through step-by-step explanations and animations. No previous electrical knowledge is required.

What you’ll cover

  • Electrical fundamentals: how circuits work and how electricity is used aboard a vessel.
  • Marine electrical systems: build a foundation for understanding everyday onboard equipment.
  • Faults and hazards: learn how to recognise common problems and understand their causes.

What you’ll gain

A grounding in marine electrics for owners, crew and aspiring technicians, with the knowledge to progress into MET 2 and build practical experience.

Study at your own paceCan be completed in around one day of concentrated study; spreading it over a few days gives you more time to absorb the material.

LEVEL 02 · MET 2

Technician

Included in your package

Build on MET 1 with a closer look at the more complex marine electrical systems found on well-equipped yachts and workboats up to 24 metres.

What you’ll cover

  • AC electrical systems: alternating current and its onboard applications.
  • Power and equipment: solar power, inverters and watermakers.
  • Electrical corrosion: galvanic and stray-current corrosion, with earlier electrical principles explored in greater depth.

What you’ll gain

A deeper understanding of marine electrical systems to support practical skills development and experience in the field—particularly useful for those working towards a marine electrical career.

Allow time to put it into practiceCan be completed in around two days of concentrated study. Around five days with shorter sessions is recommended.

LEVEL 03 · MET 3

Master Pro

Included in your package

Progress into marine electronics: how devices communicate, share information and work together across the systems found on modern yachts.

What you’ll cover

  • Marine data networks: connected devices, engine gateways and the exchange of onboard information.
  • Navigation and communications: radio equipment, navigation electronics and radar systems.
  • System integration: digital switching and industry practices aligned with NMEA 0400.

What you’ll gain

A detailed understanding of marine electronics, radio systems and data networks, with a reference you can return to when applying your knowledge.

Explore, apply and revisitAllow around five days of concentrated study, or spread your learning over longer. Return to the material as your experience develops.
Lifetime access. No rush. The suggested study times are flexible—choose a pace that works for you. Revisit all three levels as you gain experience, with instructor support to help you apply the course material to real situations.
