Let's now see a brief history of meteorology in the oceanic regatta.
We have titled it "From the BLU to Internet", from the radio to the Internet.
Because it all started with radio, the first oceanic networks were made
with single sideband, high frequency radio.
And today the races use the Internet
for all weather information.
The barometer, this was the first and let's say, the
most important meteorological instrument that has existed on ships since
the first navigators such as Slocum and Vito Dumas started sailing the oceans.
The barometer, this is a barometer from the 19th century, they carried
the clippers, which we have seen earlier in the previous lesson.
The barometer that marked the differences of pressure, the evolution of the pressure,
was the basic instrument for the navigator,
was the instrument king of all instruments.
Actually because there was only practically one, which was at first,
before the Second World War sailing was done only with barometers.
The log lines and the anemometers were very rudimentary,
they were hand anemometers and not very precise.
The barometer was what ruled life on board of the navigator.
Two emblematic sailors and the pioneers of the sport sail,
especially of the oceanic sailing and single-handed sailing, in particular.
the Canadian Joshua Slocum,
the first man to travel around the world on his own.
It took almost three years to circumnavigate the globe solo.
Slocum sailed with this
