Having a well-designed, balanced and robust electrical system on board a sailing yacht is essential. In this first chapter of the on-line book ELECTRICITY ON BOARD we will deal with the first step necessary for such design, which is the calculation of the daily electrical consumption of the equipment on board.

In the previous chapter we completed the first part of the design of our electrical system, which was to estimate the total daily consumption of the equipment we use on board. In this second chapter of the on-line book “ELECTRICITY ON BOARD” we address the next step, which is to determine the total battery capacity we need on board our sailboat.

In this third chapter of the on-line book ONBOARD ELECTRICS, we will develop a modern concept of power generation to have a robust and balanced electrical system on board, and we will analyze the different options of energy sources (solar, wind and hydro) that we have at our disposal with recommendations for ocean (bluewater) and coastal sailboats.

Tipos de inversores (onda sinusoidal pura y onda modificada), la potencia del inversor que necesito en un velero, la capacidad de baterías necesaria para el inversor, el inversor que se ajusta a mis necesidades, y un resumen de características recomendables del inversor para un velero.

Is it worth switching to LifePo4 lithium batteries on my sailboat? Is now the right time? This question doesn’t have a single or obvious answer, as it depends on several factors. To try to make this decision easier, in this chapter we’ll look at the differences, advantages, and disadvantages of lithium batteries for sailboats, along with some final recommendations.

Using the BLUETTI AC 180 portable power station onboard an ocean-going sailboat, including a description of the onboard installation, charging methods, multiple-purpose onboard use during a cruise, and a final evaluation. Includes a descriptive video and a discount coupon for this equipment.

A simple explanation of some basic electrical concepts relevant to sailors: direct and alternating current, current intensity, voltage, resistance, and power, and the relationships between these elements, with examples of their application on a sailboat.

Considerations on the protection of a DC electrical circuit, properties of fuses and circuit breakers, most commonly used types on sailboats, procedure for choosing a fuse/circuit breaker and considerations on onboard installation.

In this chapter of the online book “ON-BOARD ELECTRICITY” we will cover the following aspects of the electrical circuit wiring of a sailboat: particular characteristics of the cables in a boat’s electrical circuit, factors that affect wire sizing, and the use of tables (and the wire size calculators on the Boathowto website) to determine the thickness of each cable.
