Columbus’ discovery of America is more than a story of destiny or serendipity; it is also a story of prevailing against vicious sea weather. On his return to Spain from his first trip to America, Columbus encountered an extra-tropical cyclone, and then endured three storms that held his boats at bay for six days. In Columbus’ time, sailing the high seas was equated with having a death wish because sea weather was so unpredictable. Today, in the era of technologies such as differential GPS equipment and Navtex transmitters, that is not as much the case. Captains can now know their boat’s precise location, and whether inclement conditions exist along the sailing route.

The benefits of Navtex transmitters

Designed to feed information to small receivers that are mounted in watercraft, transmitters by Navtex help sailors avoid things that only luck could help them avoid in Columbus’ day, such as:

  • Severe weather at sea
  • Sailing route obstructions
  • Bad weather in inshore waters
  • Catastrophic geographic events
  • Icebergs in high-altitudes

The devices come in two models: the SV 1500 and the SV 3000. Both models are available in a dual system design that contains two transmitters to provide backup transmission in the event of an outage.

A Navtex navigation system is recommended for vessels that embark on long journeys outside of local waters, but they are also useful for fleets that operate in local waters in climates where weather changes happen quickly. Navtex information is delivered using two frequencies: Navtex 518 kHz – an international channel that transmits in English – and Navtex 490 kHz, which broadcasts national information in the national language. Navtex users program the receivers to receive, store, and print the information they wish to receive.

Why Implement Navtex technology?

Navtex shows that mariners need the assistance of narrow-band direct-printing telegraphy in addition to differential GPS equipmentto have all the information that they need about their location and destination. For companies and organizations that operate boats, Navtex provides the following benefits:

  • Avoidance of danger – Transmissions help mariners avoid the path of storms and avoid sailing when a storm is on its way, but out of sight.
  • A well-planned route – Mariners can plan the shipping route around obstacles such as ice, bad weather, and obstructions such as stalled ships and malfunctioning buoys.
  • Expedited travel time – Transmissions help mariners improve travel time by providing crucial information about the travel route.

Around the globe, local stations transmit Navtex messages to various types of mariners. The number of stations that transmit the messages grows almost daily.

Conclusion

Do you need the assistance of Navtex for the protection of your boats and crew, or to help protect mariners who sail in your region? If the boats take extended journeys outside of local waters, or operate in waters where the weather can change quickly, it should invest in Navtex technology to ensure that its vessels remain safe, and reach the destination as expected.
