Five layers cover the Atlantic facade (²) , from the North Sea and the Shetlands to the Canaries and the Azores, and one layer covers the Greater and Lesser Antilles.
But the most important are the three layers covering the western, central and eastern Mediterranean, which now provide detailed coverage from the Ionian Sea to the Aegean Sea. An excellent complement to the international SHOM layer. Read more →

We can only observe, for three decades, the phenomenal increase in global maritime commercial traffic, the recent increase in maritime drones, for scientific and various research purposes, automated and remotely submarines civilian, military, and even for traffickers usage, and soon the inevitable coming into service of fully unmanneded merchant ships. This evolution is directly linked to the multiplication of satellites communication and positioning means allowing remote control of mobiles at sea.
Even with containment during the Covid-19 pandemic, maritime traffic never stops. Marine Traffic view

I relayed here, in French, an article published in the British magazine Yachting Monthly (¹) on April, 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 →

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.
