Communication at Sea: What You Need to Know

Communication at Sea

Communication is an important aspect of our lives. People communicate to convey the messages they want other people to know. When people communicate, they build relationships, make friends, or keep in touch with someone close to them. As per the, communication is important to foster harmonious relationships.

At sea, the importance of communication is apparent. The safety of all the passengers as well as the crew and the vessel is dependent on how well the people on the vessel communicate. If the communication process stops, getting away from an emergency or danger will be difficult.

That said, here are some ways people can effectively communicate at sea.

Mobile Phones

Using a mobile phone is the easiest way to communicate at sea. For most of the crew members of the ship, they buy a local SIM card when they are in a new country. Since the most common form of communication today is through the internet, they can easily buy a SIM card that allows mobile data browsing.

The downside to this is that mobile phone coverage at sea is only up to 20 miles offshore.

Satellite Phone

Iridium satellite phones are proven to be effective due to their global coverage. This sat phone works anywhere in the world, even in isolated areas. These phones never get out of service range. They can be used for weather updates, emails, and voice calls. Satellite phones can be connected to a router or even into a computer, and they are proven to have helped save lives during an emergency. A satellite phone is a reliable way to communicate in case of natural disasters like floods, earthquakes, and hurricanes.

Yellowbrick Tracker

A yellowbrick tracker is also one of the most effective ways to communicate at sea. It is specifically intended for marine use. The tracker sends and updates the user’s location to a website in real time. The interval of the location update can be set from 1 minute to 12 hours. Additionally, it can be used for sending emails and SMS. The yellowbrick is a budget-friendly tracker that guarantees coverage and a reliable two-way messaging capability.

The downside is that it is battery-operated, so users will have to use the device with the default settings to maximize battery life.

SSB Radio


An SSB radio is an important attribute of marine radio channels. SSB radios are used for two-way communication. They are used to communicate with captains of other boats and the coast guards. A good feature of an SSB radio is that they are not interrupted by distance. They can easily be used for calls and messages no matter how far the distance.

However, the installation of complex circuitry comes with a high cost.


In order to communicate clearly at sea, people should use a device that is proven to be reliable and unfailing. These are important features that users should look for especially in times of hazard situations. Determining the right tool for communication is the key to maintain safety and security around the vessel. While cleaning boats, crews should also maintain communication with each other, and the methods mentioned are just the most effective.
