This article was originally published on Macworld.com by Glenn Fleishman. He explains in very precise and didactic way location services of Apple iPhone and iPad and sheds light on the data that Apple gets on our devices. As sometimes a small dose of theoretical knowledge does not affect, I give you here the full translation. Take your time, it's quite long… Read more …

I snort, install the autopilot, Get into the boat, open the logbook. I have to force myself not to read it again, Once again, your latest annotations. On the virgin page facing them, I write : Friday 5 June 2009. Cast off Port Camargue 5 Morning hours. 15 Anemometer knots. 10 at log. Compass on 114 Degrees. Calm seas. ”

iNavX and SiiTech AIS server
iNavX allows you to connect, since version 3.1.7 from February the 11 October 2010, to the data server AIS SiiTech which I talked about in a previous post (¹). The interest of this service remained questionable in France because of the poor coverage of our coasts. That could change.
Indeed, the number of SiiTech ground stations is increasing, the Channel coasts are now well covered, and the Atlantic coast should be gradually equipped (²).
In addition, The version 3.2.4 of iNavX comes with an improvement that makes a revival of interest for this feature : it is now available to select the origin point of AIS data from SiiTech server, or the position of the ship (that of the iPhone/iPad used), or a previously created waypoint. The reception radius being about 30 nautical miles around place of origin, this allows for a significant increase in the coverage of AIS data reception.
Are the tidal predictions reliable ?
All navigation software offer predictions of tides, more or less long range, that cover the coasts of the whole world. Where come these predictions from ? How are they established ? What is their reliability ? These are all questions that any conscientious yachtman is entitled to ask.

iTabNav.fr
This is an excellent initiative that we owe to Dominique Gauthier : iTabNav.fr is a new French e-commerce website mainly dedicated to iPad (and the iPhone) accessories useful in’marine usage of these devices.
Rather than looking on Google for e-commerce websites overseas, you can now go to a French specialized website. Dominique Gauthier did not hesitate to get my opinion on the technical aspects of his choice of accessories, being himself user and boater.
iTabNav.fr has been open for a few days, its catalog will gradually grow, I salute his initiative and wish him good luck.

Connected to a Miniplex-2Wi by ShipModul ou un WLN10 device, the data thus converted will be sent via WiFi to iNavX. Read more …

Reading : "The Voyage to Polynesia" by Jean-Jo Scemla
I had to embark in a few days for a convoying from Mediterranean to Polynesia. Unfortunately, The postponement of the departure to the end of the month and the professional constraints of returning imperatively at the beginning of May have just forced me to give up this trip. Bitter disappointment…
If you can't go there, It is always possible to experience it on paper. Following the "Voyage of Magellan" that I mentioned last December, I suggest a book that I discovered some ten years ago. A book to make you spend the winter by the fire, make you want to discover these islands scattered in the middle of the largest ocean on our planet, through their history told by the greatest travellers of past centuries.
