Category: On-board electricity

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.

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.

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.

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.
