I relayed here, in French, an article published in the British magazine Yachting Monthly (¹) on March 30 th. The subject deals with the debate between paper charts and electronic navigation, by stating many truths, but also sometimes one or two untruths. The purpose has the merit of presenting contrasting arguments, and to obtain the opinion of recognized UK's professional boaters. Since the confinement imposes time constraints on us, let's take this opportunity to enjoy this instructive reading.… Read more →

In 2020 the iPad training with ACM Catamaran are renewed and extended. ACM also began the decade with a new website much more user friendly, aesthetic and efficient. I manage training "Navigating with Weather4D Routing & Navigation with iPad" in onboard weekend on one of cruising school catamarans (Lagoon 380) starting from the base of Hyères – The Gapeau. From 3 up to 6 trainees for these intensive courses that are very successful for several years.
The Calendar 2020. is available and registrations open. Read more →

Iridium GO! cruising
Since it appeared on the market in September 2014 (Eh, yes, 5 years ago !) this device an indisputable ergonomics and excellent quality / price ratio has become a must for sailors out at sea. Easy to implement, without the need for an external antenna (except metal hull) it can be used inside the boat.
A test several weeks, conducted in October and November 2016 during a transatlantic delivery, had already demonstrated its ability to download GRIB weather files and frontology maps despite the low rate (about 10 KB / mn). With the new Iridium NEXT constellation (¹) we notice since 2019 a real improvement in the global coverage without satellite disconnection.

For several years it is possible to integrate iPads and other mobile devices using Wi-Fi to onboard instruments. This enables navigation applications, not only receive all sensor data : log, anemometer, sounder, AIS, etc., but also to send their own navigation data to instruments, as, in example, to control an autopilot.
This integration is through devices called “gateways” or “routers” that connect to networks of instruments, receive the data circulating through these networks, and transceive in Wi-Fi to tablets and smartphones. Some navigation applications are being developed to process this data and transform mobile devices into real navigation centers. Read more →
