The blog
I relay here an article published in 2014 on the blog of Digital Yacht which provides an excellent discussion on choosing which antenna to install for an AIS transceiver. Below you will find a transcription freely adapted by me..
One of the most common questions asked by boaters who want to purchase a Class B AIS transponder is : which VHF antenna to use ? Read more …
I introduced last May The Nomad, a portable AIS transceiver designed by Digital Yacht. I had to wait until the end of the summer to have the opportunity to test in real situation this device that had been entrusted to me by the manufacturer. I can already say that I was conquered.
I conducted the test in two phases. The first in my home port of St-Vaast-La-Hougue in my own boat, to the pontoon, and at low tide, the port doors closed - the context is important - for the commissioning of the reception only. The second at sea, in Roussillon, with setting the transmission service. Read more …

For the first time since 5 years I'm not moving to the Paris Nautic boat show. And for the first time I am not "glued" ten hours a day to a 9 m². And so for the first time I take the time to be interested - remotely, without jostling, without air conditioning, without pollution in Paris – to various products related to my field of investigation and which have caught my attention.
Some concern security, others useful accessories, all of them have to do with mobile devices, smartphones or tablets, and some are really innovative.
With the progressive generalization of the AIS (transceivers) aboard our pleasure boats (¹), and their obligatory presence on board a large proportion of commercial ships, capacities for display and processing of targets (surrounding vessels equipped with a transceiver) have significantly improved our security. Still need to know how to interpret this information that, in high-traffic areas, can quickly become a real headache.
In such a situation, better have a quick diagnosis of the risk of collision ! (Weather4D 2.0)
The Department of Ecology, Sustainable Development and Energy, published on 4 August a Boating Safety Alert about LEDs bulbs (¹). The text warns boaters on the risks of radio interference found where the VHF antennas are close to navigation lights or bridge lamps equipped with LEDs bulbs. Read more …

AIS takes a growing place, for two or three years, in the concerns of leisure boaters. Several articles refer to it in this blog, as for equipment as for applications available for our Mac, iPad or iPhone.
Note to neophytes in this subject, or to confirm the knowledge of the most informed of you, it seemed useful to clarify what the AIS means, while just held in Hamburg, the 15 and 16 of June, the international conference AIS Summit. Read more …
