Why is marine electronics so important?
Marine electronics show the pilot all the onboard information. The log and speedometer provide the speed, the sounder indicates the depth, the anemometer gives the wind strength and direction, the VHF communicates, the GPS positions you, the radar shows you dangers, and the AIS signals other boats. Collected on one or more screens, the embedded electronics systems are part of the safety devices, protecting you during navigation.
At sea, it is very important to know your position, direction, as well as the speed and duration of navigation. Long ago, sailors obtained this information by observing the position of the sun and stars. Today, there are tools capable of providing the necessary information for optimal navigation in real-time.
Below we see some of the essential tools for not only comfortable but also safe navigation.
The GPS
The GPS is a fundamental element on board a boat, indicating your position through satellite signals. It makes navigation more comfortable, and you will always know where you are, allowing you to avoid risky areas.
The magnetic compass
The magnetic compass is used to indicate the course followed by the boat. The compass is mandatory for all navigation beyond two miles from the coast. It does not depend on power supply, so you can keep the course even in the absence of current.
The radar
The radar is a signaling system based on sending and receiving radio waves that determine the position and speed of an object detected around the boat. It also allows you to position yourself and know the speed of the boat’s movement. It is very useful for night or foggy navigation.
The sounder
The sounder allows you to know the depth of the water under the boat and works by returning the echo. Besides its utility for fishing and diving, it acts as a warning to avoid running aground near coasts or shallow seabeds.
On Raymarine, you can find these tools and much more. On this online platform, you can access a wide range of nautical accessories and equipment of all kinds.
