Course Topics

This course is about battery types and charging. The course covers types of batteries, sizes, consumer batteries, starter batteries, open/closed cells, AGM, GEL, and LI-ON.

Power to the bow thruster, anchor winch, and winch are reviewed along with cable pulls rules, including resistance in cables and batteries’ placement. 

For example, it may be a good idea to have an extra battery under the berth.

Recommendations for charging voltage, charger size, when to charge the battery, and DC-DC converter/charger for li-on batteries. 

Advice is also given on winter storage, avoiding sulphation, and when a battery needs to be replaced.

This course is about the switchboard and its connections. It includes power consumption and voltage drop in cables.

The switchboard’s 230V and 12V connections are reviewed as well as the location of the main fuse. 

Examples of different paintings from Bavaria, Hanse, and Philippi are shown. 

Busbars and fair distribution of current are reviewed.

Bow thrusters are large power draws, and the special connection requirements are reviewed. 

Also, the connection of a bilge pump is treated, which should be active even if the rest of the boat is switched off.

This course deals with 230V on the boat, including shore power, solar panels, and wind generator.

You will learn about safety around general use and work with shore power. 

Did you know, for example, that you should always connect the 230V cable in the boat first and then on land? It can be life-threatening if you are so unlucky to fall into the water with an attached cable.

The special requirements for 230V installations on the boat are reviewed. If, for example, you have other 230V equipment than a double insulated charger onboard, there is a requirement that there must be an electrical panel with an HPFI relay. 

Also, the course goes into detail with requirements and good advice for cable types, connectors, connections, etc.

You will also learn about inverters and connecting these. An inverter converts 12V or 24V from the battery bank to 230V. The course covers how to use a converter and the difference between good and less good quality inverters. It also covers what to be aware of when choosing an inverter and how they are connected correctly.

Finally, the course reviews solar panels and wind generators. Here the difference between the types, efficiency, installation, connection of several panels, and regulations are explained.

This course covers low-speed networks: NMEA0183, NMEA2000, Seatalk NG, and Simnet. The course also goes in-depth with high-speed networks such as LAN and wireless networking. 

Also, the exchange of motor data over a J1939 network and connection to NMEA2000 is reviewed.

Wire colors, terminations, drop cables, and installation, including backbone, are reviewed. It explains how to connect different equipment, e.g., GPS to VHF.

Examples are shown of the communication phrases that are sent between different equipment on board. Here is how a PC can be used to display the sentences and how to generally troubleshoot networks.

 In this course, you will learn about galvanic corrosion and grounding. 

When two different metals are placed in a liquid that can conduct a current (a so-called electrolyte), a current will be drawn, which causes one metal to be destroyed. Saltwater could, for example, be such an electrolyte, and it can therefore cause corrosion in the boat. 

The corrosion is due to the electrochemical voltage range reviewed in the course. It also covers how galvanic current occurs.

The course also shows how to measure whether a galvanic current is flowing (and whether there is corrosion). Prevention of corrosion with corrosion zinc is also addressed, including its function, location, treatment, and grinding.

In addition to the galvanic current, grounding and ground plane are also reviewed in this course. Some types of equipment require grounding to function correctly. For example, radar and MF/HF radio. The function and necessity of the ground plane are reviewed and how it is connected and mounted correctly.

This course focuses on VHF radio and VHF antennas. The VHF radio’s overall function as a safety device is reviewed, including Digital Selective Calling (DCS). 

The course also explains how a VHF radio is maintained, where it can be used, and VHF’s requirements on leisure boats.

In the antenna part, the course goes in-depth with VHF antennas, antenna cables, 50 ohms vs. 75 ohms, losses in these, and how the associated connectors are mounted on the cable. 

The course covers how to choose the right antenna and the suitable cable, including how to adapt the cable. 

Also, losses in antenna cables, some theories of standing wave conditions, and the radio waves range are reviewed. 

Finally, an example of troubleshooting a VHF system with AIS is also given.

This course focuses on medium wave (MF) and short wave (HF) radio, SSB, and DSC. The range and use of the various radio systems are reviewed.

Also, the different MF and HF antenna types are explained.

Safety equipment such as EPIRB, PLB, AIS-MOB (personal beacons), and SART radar are reviewed. 

Besides, AIS, which is a critical security system, is reviewed. The course covers what it is, how it works, and how to use it.

This course covers various satellite-related systems. It includes satellite phones and Iridium communications, including SMS, email, and data.

Various options for the internet onboard are also reviewed. In addition to satellites, which covers most of the earth, it is possible to have faster coastal internet in the north via NET1.

The course covers tracking and monitoring via Vsat, Maretron, and Actisense.

The course also reviews how a PC-based system can be used as a chart plotter, GPS, anemometer, etc.

This course is about how to examine the electronics on board, especially before buying a boat. 

Besides, various aspects of autopilot troubleshooting and setup are reviewed.

Many things can be checked in connection with the purchase of a used boat. The course explains where to pay special attention. It can be things like:

  • Has there been water in the boat?
  • Batteries – what is the voltage after standing ½-1 hour without charging?
  • What age and condition do the autopilot, plotter, and other instruments have?
  • What does it look like behind the switchboard?
  • How are the cables and wires around the boat in general?
  • What is the condition of pumps?

I attended your first Q&A session and was so impressed I signed up for the course, mainly to keep myself up to date.

The quality of the instruction and course materials are first class and the course is great value.

I would be delighted to recommend your course to anyone wishing to get a greater understanding of the increasingly complex systems on boat yachts and motor cruisers.

Thank you once again and kindest regards from Scotland.
