Boat Electrics 101
Safe & Reliable DC Systems
Dr. Jan C. Athenstädt
We are Nigel, Jan & Michael.
We help you understand, extend, and redo your boat electrics.
The right way.
I now understand all the electrical systems and how everything works together.
Bob Russell - S/V Spartina
Jan, Nigel & Michael,
I want to let you know how impressed I was with the BoatHowTo course!!
Having purchased a new to me Island Packet 350 this year, I was overwhelmed with all electrical systems on the boat!
Modern cursing boats have become very complex and I was lost!
Having taken your Boat Electrics 101 course I now understand all the electrical systems and how everything works together.
From the very basics, through creating a detailed circuit diagrams of the electrical systems on my boat, my knowledge is years ahead of where I thought it would be at this point.
Thanks for a wonderful, extremely useful (and fun) course that takes a lot of the mystery out of sailboat electrical systems!!
Boat electrics is not rocket science...
...but it still has to be DONE RIGHT!
Electrical systems on boats have become more and more complex over recent years.
Even moderately equipped boats today rely completely on their electrical system. A loss of power means in most cases an emergency at sea. (Or do you still have a sextant and all nautical almanacs on board?)
Boat electrics are often poorly understood, despite being such a vital part of the operation of a boat.
The good news: It's not that hard!
With a bit of time and a commitment to learning, everybody who mastered basic high-school math and physics will be able to understand the DC system on a boat. All it takes is a reliable and easy to understand source of information.
You want to understand your system?
Clearly expressed and illustrated, the course is full of practical information
Derek Nowek - Falmouth, ME
The Boat Electrics 101 course is a fantastic resource for beginners like myself who know little about electricity and even less about boats electrical systems. Clearly expressed and illustrated, the course is full of practical information presented in a way that makes boat electrical systems understandable. Thank you for putting it together.
The majority of fires that start on boats
are caused by the electrical system!
Understanding your boat's DC system can significantly improve the safety of your boat!
Unfortunately, many owners have only a vague understanding of their boat's electrical system. Or, even worse: They think they know how to install a system and end up making damaging mistakes...
...and teach others these mistakes in blogs or on YouTube.
YouTube is full of videos about Boat Electrics
– many are wrong and some are dangerous!
The internet is a great source of information. And in recent years, many people have shared their experience installing or fixing electrical problems on their boats.
The problem: Many of those people are not professionals!
It's easy to put a professionally looking video on YouTube...
...but it is hard to tell, if this actually is professional advice - or misleading BS.
If you follow bad advice on how to varnish teak and you end up with a mess, in the worst case you lose time and a bit of money.
If you follow bad advice on how to connect batteries and your boat ends up in flames, this is a different story.
A typical example of bad advice...
...is soldering. Soldering is often praised as a great way of connecting wires. On a boat, it is not. Soldered connections are rigid and tend to break when exposed to the vibrations common on boats.
This is why electrical installation standards from the American Boat and Yacht Council (ABYC) and the European International Organization for Standardization (ISO) both explicitly prohibit soldering as the only means of connection!
You want know how to do it right?
Your brand new boat is properly wired...
...or MAYBE NOT?
When visiting boat shows, Nigel likes to inspect the electrical systems on brand new boats. Unfortunately, this has become quite frustrating: a shockingly high number of production boats come with badly installed electrics – straight from the boatyard.
These batteries were installed on a brand new boat. What's wrong here?
- Inadequate support against sliding off the shelf
- Parallel connections badly designed - this will lead to premature battery death
- Too many cables on the positive battery post
- No overcurrent protection devices anywhere near the positive battery pole
This installation might look neat at first glance. But:
It is unprofessional and asking for trouble!
You want to assess your system?
I now feel empowered to research and undertake this work on my own.
Mark Sweetnam - Ireland
Wow, what an outstanding course – thank you so much. I intensively studied each lesson, took notes (frequently pausing the video to do so), read and made sure I fully understood the lecture notes and then likewise all comments. The entire course took me about 6 full days to complete. In my own case I have owned a 30 year old Swedish boat (Najad) for the past 10 years. It has both 12V and 24V house systems, with two alternators. I got the batteries replaced about 8 years ago (with Victron AGM) but am now looking to upgrade the electrics in numerous ways, and obviously to audit and rectify any OCP or other shortcomings. New batteries will obviously be needed shortly but I also want to add solar. But mainly I want to either get rid of the 12V bank (and use DC-DC converters for the 12V house load) or add 12V-24V-B2B charging both for redundancy and to use full capacity of both 12V and 24V alternators and shore power battery chargers. I now feel empowered to research and undertake this work on my own. Thanks again.
Who or what are ABYC and ISO?
The ABYC E-11 and the ISO 13297 standards cover the principal electrical systems on small craft.
Even though they are legally non-binding, they are based on decades of experience of hundreds of experts in the field.
So, instead of trying to figure things out for yourself (with potentially disastrous consequences), it is a good idea to follow these standards as closely as possible.
All three of us are members of various standards committees of the ABYC and ISO, Nigel and Michael for decades. Everything we teach at BOATHOWTO is compliant with ABYC and ISO standards.
There is no one who knows the standards better than us.
The American Boat & Yacht Council (ABYC) is a non-profit, member organization that develops voluntary global safety standards for the design, construction, maintenance, and repair of recreational boats. As an independent consensus-based body, the industry experts at the ABYC (including Nigel Calder from BOATHOWTO) work together with the sole purpose of protecting the safety of the boating public.
The ABYC’s Standards and Technical Information Reports for Small Craft cover all major boat systems. The development and regular review of these standards provide boat building guidelines that correlate directly with a significant reduction in the number of boating accidents over the past six decades.
The International Organization for Standardization (ISO) develops high quality voluntary International Standards. The sub-group of the ISO that addresses small craft (up to 24m/70 feet), is known as Technical Committee (TC)188 (of which Michael Herrmann and Jan Athenstädt from BOATHOWTO are both members). This committee has developed a set of standards that are closely aligned with the ABYC standards.
With respect to boat electrical systems the principal difference between the ABYC and ISO standards lies in the fact that the ABYC standards tend to be more detailed. In order to provide the most detailed information in our lessons, we follow the ABYC standards. Where there are minor disagreements with the ISO (only a handful) we point these out.
You want your electrics to comply with ISO & ABYC standards?

The course has given me the knowledge to make better choices
Tommy Kaine - SV Alboe
Just a note to say how terrific the Boat Electronics 101 course is. It is very comprehensive. It has empowered me to refit my 1976 Westsail 32 original electrical system. Though I am outsourcing some of the work, the course has given me the knowledge to make better choices, do my portion of the project, and have a smart conversation with the contractors. Thanks for all your hard work and keep it up!

In this recorded presentation, Nigel explains you how to use a multimeter for simple troubleshooting tasks.
Learn which are the most common causes of electrical faults and what tools we need to trace them down.
Voltage measurements are the most important way to trace faults. This is why this is the most extensive lesson of this module.
If a voltage measurement does not help us track down a fault, resistance measurements might be a solution.
With a clamp meter, it is possible to make current measurements without disconnecting any terminal. We show you cases when this helps with troubleshooting.
In this talk, Nigel gives an overview of the challenges in designing a safe and reliable DC system. The talk was originally recorded as part of the IBEX 2021 Seminar Series.
Nigel Calder gives an update on today's battery technology. Including important, but often overlooked, considerations on the topic of lithium-ion vs. lead-acid batteries.
It’s excellent value for money
Martin L. -
Perhaps some might say the course isn’t particularly cheap but I would argue the cost versus the excellent work that has been done in the creation of the course and in my view at least, it’s excellent value for money. It is also a reminder that there are things we may think we know, until you complete the course you may well find there are things you didn’t know or had assumed differently.
So thanks for all your hard work and I do hope that many will learn better and safer ways and take a much closer look and inspection of their own electrical systems. I certainly have. There is a great deal of information to absorb and I have no doubt I will be returning again and again to re-read various sections of the course.
