A seamless progression from the level 1 course, study the finer points of more complex on board electrical systems - find and fix faults.  

MECO Boat & Yacht Electrical Course Level 2

 

The Meco Level 2 Boat & Yacht Electrical course studies the on-board electrical systems of a well equipped self sufficient ocean going live-aboard vessel. It is important that the basics from the level 1 course are thoroughly understood before embarking on the level 2 course, as these foundational elements will be built, and relied upon throughout.

 

Key points:

 

  • Self paced, start training right away.
  • Fully online, with full instructor support throughout.
  • Learn the intricacies of the electrical system.
  • Pre course requirements : B.Y.E Level 1 course
  • Duration of course: Unlimited, you can take as long as you require. 

 

Further Details:

The MECO training courses are aimed primarily at boat owners, skippers and crew, but many of our students enrol for pre study towards professional industry standard technician courses from the ABYC or BMEEA, or for super yacht crew studying towards IMO /  MCA engineering courses. 

 

The courses are designed to help you fully understand the on board electrical system, this begins to get fairly complex when we introduce multiple sources of AC power such as Shore-power, Generators, Inverters, and then to complicate matters further - multiple sources of DC power too, such as Solar, Wind, Alternators, and Battery chargers. 

 

The overall electrical systems on a well equipped self sufficient vessel seems impossible to understand -  when it's a mass of cables, how ever neatly it may be wired - this level 2 course serves to unravel the mystery by considering each and every circuit as an individual entity first, once that stage is understood, we then consider how this subsystem fits into the wider electrical system, what maintenance it needs, how it can fail, and how to find and fix faults. Each subsystem, however complex, is rendered down to its lowest basic requirements - volts, amps, and ohms.

 

What this course is NOT!

This course is NOT a How To re-wire your boat guide, and it is strongly recommend to enlist professionals to do this, even if just on a consulting / inspection basis; even experienced marine electricians consult each other on larger projects. 

 

What this course IS

How to fully understand the finer points of how marine electrical devices work,  how they should be safely / legally / efficiently interconnected to work in harmony with each other, and how to prevent, find and fix faults. . 

 

 

The Level 2 course covers the finer points of how each electrical subsystem works, but also covers the much wider topic of how they can be efficiently / legally / safely interfaced to work in harmony with the wider on board electrical system. Many How To guides use a one size fits all approach, this never works in the complex world of marine electrics! Each boat is different, each make, model, version of new kit is different, and it has to interface with various era's, makes and models of older equipment, the distance between the equipment plays a role in cable sizing, the size of the kit, how you use the vessel..... there are too many variables for a one size fits all approach to fitting marine equipment!

 

General ability after the course:

  • Identify electrical potential dangers, and know when to call in the professionals, 
  • Hold a balanced conversation with engineers, technicians, and marine electricians
  • Understand the finer points of how marine electrical devices work, and how they can fail
  • Understand how key subsystems work in harmony with the wider electrical system
  • Prevent, find and fix common basic electrical faults
  • Evaluate how safe the electrical system is
  • Identify key non conformances of the electrical system with reference to the relevant class, code, or standard
  • Be able to make specific recommendations as to how the electrical system could be improved
  • Evaluate an electrical system and build a spares wish list in priority order
  • Decide what test equipment is required to carry on board based on the specific  installation
