It saddens me to end the year with a critical article, but the subject deserves it. I wrote in December 2016 (*) a sincerely positive appreciation of the evolution of the application Guides Escales 2017 - Bloc Marine digital version by Figaro Nautisme editions - compared to 2016. But for edition 2018, is unfortunately go back, supply regress and severe rate increase.
Unlike the print edition you can keep several years in your boat library, the annual update of the application Guides Escales clears all purchased regions the previous year. It is therefore not a purchase but an annual subscription, nuance!. And that's not all…
[Updated 2022] The Escales Guide has been withdrawn from sale.
Ultrasonic anemometers-weathervanes for yachting came up just over 15 years old. Among the best known we can cite those of the American Airmar and French LCJ Sensors. Equipped with sophisticated electronics, these sensors without moving mechanical parts have the double advantage of being much more robust than traditional sensors, and provide much more precise data. They can also integrate other sensors as a barometer, gyroscope, electronic compass and sometimes even GPS.
Among the many new features brought by iOS 11, I particularly appreciated the improvement in the multitasking functions. The addition of a retractable "Dock" in the MacOS way, the "SlideOver" function combined with the "SplitView" function already present in iOS 10. This will greatly improve the use of navigation apps.
