Communication at sea is never a convenience but rather a necessity, without which a lot like coordinating with ports, ensuring smooth navigation, or sending emergency distress signals may not be possible, which is to say, in simpler terms, it is like knowingly putting the passenger’s life at risk. Therefore, having VHF radios in vessels is more or less like ensuring reliable communication at sea. VHF radios provide a secure and efficient means of connectivity for vessels of all sizes.

To get your ship equipped with advanced, internationally compliant communication systems, first and foremost you need to get acquainted with a trusted marine radio supplier in Dubai. 

Stick in to know more about the subject and get acquainted with such a supplier as mentioned above and maybe make a purchase or add to your bucket list for later.

Why do we need VHF radios for proper maritime communication?

• It is helpful for giving an immediate response during emergencies. If you are well aware of the mandates of the International Maritime Organization, you will know that vessels are required to adhere to certain strict communication standards, of which immediate response during emergencies is a key factor. VHF radios, particularly those with Digital Selective Calling (DSC), adhere highly to this rule of immediate response during emergencies, which is also a Global Maritime Distress and Safety System (GMDSS) regulation.

•  Enables real-time communication, paving the way for real-time coordination. Every boat or vessel at sea relies on VHF radios for real-time communication for safety as well as various other purposes, like smooth and flawless interactions with port authorities, coastal stations, or even other vessels. This significantly reduces the risk and enables much more efficient operation at the sea.

• Supports carrying out clear and reliable communication at sea. For decades, satellite phones were the go-to choice for communication at sea up until the arrival of VHF radios. However, VHF radios provide instant as well as interference-free communication within a specified range, unlike satellite phones, which get interfered every now and then. These VHF radios are highly effective for short-to-medium-range communication and thus make them an indispensable choice while navigating through congested waters.

• Provides assistance in instances of emergency without delays. VHF radios are a lifesaver in times of crisis like no other equipment, as they possess Digital Selective Calling (DSC) technology that enables vessels to send automatic distress alerts at just the push of a button in times of emergency of any sort. This technology will therefore allow vessels to turn for help to rescue authorities as well as nearby vessels without any delays.

Categorizing VHF Radios based on Classes and Features

Category 1: Class A VHF Radios

High power output, extended range, and DSC functionality are the main highlights of Class A VHF radios. These are intended mainly for large commercial vessels for international shipping.

Category 2: Class D VHF Radios

Class D VHF Radios, unlike Class A VHF radios, only have basic DSC capabilities and are more compact as well as more affordable than Class A. These are intended for leisure boats, fishing vessels, or small ships.

Category 3 & 4: Fixed vs. Handheld VHF Radios

Fixed VHF Radios: these are installed permanently on the ship’s bridge and offer a higher power output (up to 25 watts) as well as a better range.

Handheld VHF Radios: These are portable and battery-powered VHF radios, made for small boats, lifeboats, or simply for backup communication in case of any power failures.

How do you choose the right VHF radio for your vessel?

There are several things to consider before committing to purchasing or booking a VHF radio, some of which are concerned with power and features while others comply with international safety standards. However, the first thing to look for in a VHF radio is indeed whether it possesses the power and range you anticipate it to possess. High-voltage radios, needless to say, offer longer communication ranges. The second thing to look for is if a VHF radio actually has DSC capabilities. DSC, or Digital Selective Calling, is a technology that allows vessels to enable automated distress alerts in situations of emergency with just a single click of a button. Another thing, if it allows for integration into other systems, may not be as important as the above ones; however, it is an added advantage to have, as some radios can connect to navigation, safety, and VDR systems all at once. The final thing to look up is if it hits regulatory compliance, that is, the VHF radio you are about to purchase meets the IMO and ITU standards. If all these are satisfied, you are good to go with your purchase as long as you do it from a reputable marine radio survey in UAE.

Final thoughts

Navigating through a busy port is no easy task, nor is coordinating with crew members or, at worst, responding during situations of emergency. The good thing is that if your vessel owned a high-quality VHF radio, all these would no longer be a herculean task. With a VHF radio on board, you could sail with a lot more confidence and a lot less stress.
