Have you ever wondered how people on boats or ships conveyed that they needed help?
For generations, each region relied on various crude ways of expressing distress calls. Only a handful of people can understand.
They used visual and auditory signals, depending on foghorns and flags, to convey the call.
When learning kayaking one of my instructors taught me the paddle signals.
To convey your state to others around you since verbal exchange often gets complicated in a water body. It got me thinking about the distress signals such as SOS meaning, and modern-day use.
The Famous SOS Signal
When someone in the year 2020 goes ahead and uses SOS together like that, we understand its intent. It means that the person signaling it through any means needs some assistance. SOS has become a universally understood message.
Given how this was not the case two centuries ago, it says much about the extent of maritime dangers and rescue before that.
What Does SOS Stand For?
“SOS” is an abbreviation for “Save Our Souls” or “Save Our Ship.”
Or so we all thought.
It turns out, like me, many people believe SOS stands for something. “Save Our Souls” and “Save Our Ship” phrases are only backronyms. They are not abbreviations. They have been incorrectly conjoined with the Morse code term SOS.
The History of SOS Signals And Morse Code
As soon as radio transmission and telegraph services improved in the mid-1800s, people started using them to communicate at sea.
Samuel Morse (1791 – 1872) and Alfred Vail (1807 – 1859)
Using the telegraphic principles, Samuel Morse and Alfred Vail came up with the Morse code in 1838.
Morse code assigns letters, numbers, special characters into two symbols. These symbols are dots or short marks (.) and dashes or long marks (-). Frequency of usage determines the use of dots and dashes.
The combination of these two can translate any phrases, like the combination on zero (0) and one (1) can translate any number in binary code.
Morse Code or Vail Code?
So, who is the inventor of the morse code?Even if it is well known attributed to Samuel Morse, the work of Alfred Vail and contribution make some historian saying than he is the inventor.
To be fair, “that code” wouldn’t have been possible without both of them.
The technical contribution of Alfred Vail is huge. See an interesting article on the subject and the narration of William Baxter, Vail’s assistant during the invention. William Baxter narrated that they worked nights and days for the construction for the new machinery.
So, if you closely read the narration of William, you can notice that when building the device, the idea and the reality merged so new ideas and adaptation come up mostly from Alfred Vail which influenced the final version of the code.
Since telegraphic wires meant people could transmit messages over long distances in a short time, countries started investing in creating a network of telegraph wires.
That way of communicate spread out across the globe, connecting continents to continents. Since there was no uniform regulatory body to authorize what the distress codes are, many organizations came up with their signals. The most famous of them is the “CQD” signal, used by the Marconi Company.
How Did It Become Known as SOS?
The Germans were the first to generate the signals “… —…” to signal help. These signals were easy to recognize. They translate to a “di di dit, dah dah dah, di di dit” from radio signals.
And in the International Morse code, they translate into English letters of S and O.
This is how the letters SOS became the famous distress call signals.
SOS is easy to interpret if written down: it is the same from the right side as it is from the left when you read it. The same is the case with upside down.We call it an ambigram.
Another rare ambigram of that sort is NOON. Do you have one? I think the answer in NON (NO in French).Ok I will not abuse the jokes.
This clever property makes SOS signal the common signaling technique adopted , and not only in sailing.
SOS as International Distress Signal
On 3rd October 1906, the Marconi Company and German Telefunk organizations understood using “SOS” signals. The signal was universally adopted as International Distress Signal on 1st July 1908.
SOS Used for The First Time
The first ship to generate an SOS distress call was the RMS Slavonia on 10th June 1909 near the Azores. The steamer SS Arapahoe was soon followed on 11th August 1909 near North Carolina, USA.
United Wireless Telegraph Company received these signals in North Carolina.
Although SOS was adopted in 1908, the new distress signal took some years to become mainstream finally.
Visual Distress Signals (VSD)
With the advent of the satellite age, the Morse code slowly faded from the maritime gestures. Instead, the standard “Mayday” command has replaced the SOS call. This conversion happened in 1927.
If you are thinking about boating, knowledge of visual distress signals (VSDs) is necessary. It would help if you also learned to interpret it correctly. Various modern-day SOS calls require visual and auditory cues, e.g., flares, distress torch lights, mirror reflections, whistles, and flags. Besides, GPS tracking and long-distance radio calling are also commonly used in seas and oceans.
Types of Modern-day SOS calls
There are three main signals you can give off, but there are certain conditions.
- Hand-held red flares (3 in number) [during day and night]
- Electric distress light (only 1) [only night]
- Hand-held flare (1) and parachute flares (2) [during day and night]
When you go for kayaking or boating, always make sure you have a small bag that contains a signal mirror, signal torch, night signal kit, a few aerial, parachute, and hand-held flares, orange and red flags to represent danger or help and and whistle. Yes it seems to be a lot but anyone of those can be the cause to save your life.
SOS signal with your smartphone
To generate the dot (.) use the flash shortly – one second – and for the dash (-) use the flash longer – two seconds
You Saw a Distress Signal — Now What?
If you are out in the sea in a boat or ship and you see a flare in the sky, try to identify the position and distance. You can do this by holding your arm straight out in front of you and closing your fist. Try to guess the flare’s height compared to the fist you make, with the thumb pointing out. It is best to measure this with the horizon aligning with your fist’s base, thumb pointing skyward.
Try to identify If the flare was a half, one, or two fists. If you see any other visual distress signals, try to figure out if you are equipped enough to help. It is better to report such cases to the Coast Guard and let the professionals handle such dangerous situations.
