A test onboard with Navigation Mac

During a somewhat sad weekend in January, we joined the port of L'Herbaudière, Isle of Noirmoutier, via the picturesque Gois passage at low tide.

We, that is to say, a boating journalist, my wife and myself.

Welcomed by two “naturals” of the country, Henri and Jean-Etienne. The latter putting his superb Océanis at our disposal 347 for the first on-board test, In France, navigation applications on Mac, iPad and iPhone. A great first, somehow.

The scenario

The scenario called for a two-act test :

Act 1 :

MacENC on a MacBook, an GPS BU-353 connected to a USB port, a receiver AIS RX Carbon (True Heading) connected to a second USB port. MacENC configured to transmit GPS data and AIS targets over TCP/IP to onboard iPhones and iPads : 3 iPad WiFi 3G models 5 iPhone 3G, 3GS and 4, No less !

Macenc and iPad

Act 2 :

March, the GPS Raymarine onboard power, The’AIS RX Carbon and a wind-gear NASA Clipper connected to a multiplexer Standard iMux (Brookhouse) transmitting NMEA data directly over WiFi to an iPad.

Instruments

Brookhouse's iMux multiplexer and True Heading's AIS RX Carbon

The making-off :

After the necessary tinkering to install all this equipment on Jean-Etienne's chart table, that took us a short day, we made a round trip to Pornic in a light south/south-east breeze and a stubborn mist, barely evaporated on the way back.

The movie :

Sorry, There will be no preview ! Must await a future issue of the magazine "Boats" to discover the result of this exciting event. [Update] No. 635 – Avril 2011.

A big thank you to our skipper for the kindness of his welcome, both at sea and at home, in the heart of the Bois de la Chaise. Thanks to Henri for organizing all this, to Damien for his excellent company, to my wife for her patience in the middle of all these technical-maritime geeks and their abstruse language. And finally I do not forget the aperitif offered by the friendly leaders SRIN (Société des Régates de l'Ile de Noirmoutier).

Looking forward to seeing you again !

  1. Bonjour,
    here is my experience with Inavx on Iphone. I had the opportunity to drive and use the weather in Turkey, in Greece, from the top of the Iselmeer in Holland via Ostend to St-Malo, Brigthon, Cowes, in Scotland from Oban to Stornoway, in Polynesia from Tahiti to Bora-Bora via Morea, Huahine, Taha, etc,.
    I can say that I didn't have any problems regarding the nav. nor for the weather.
    I sailed in parallel with different systems existing on boats or portable (Garmin) and found no difference in accuracy on the maps. On the other hand I find Inavx more ergonomic.
    What is sorely lacking, it's the currents….

  2. Don't wait for the article : Start !
    I ordered an iMux at the end of December in New Zealand, received about ten days later, installed yesterday. On a RayMarine installation, Three wires to connect : " + ”, " – and the yellow thread of Seatalk. Immediate network start-up, configuration according to the information provided by Francis and the information is available on the iNavX of my iPhone !
    I think I'll end up falling for an iPad……..

  3. Bonjour
    Thank you for this information. In which "boat" number will the test appear?

    My cordial greetings

    Manou

  4. To all of you , Passionate about the sea, I hope that your navigation accompanied by your "great tools", whose usefulness and ease I do not deny, do you reach Nirvana boating , in a society that is increasingly deteriorating, but when you are lucky enough to have a passion for the sea, boat, kayaking, computer, etc.…… We escape this unfortunately too restricted universe of the Earth, this land that could be magnificent, which sometimes is, but at sea one escapes, even if it's on iPads, etc,… and thank you for your complicity in Francis' passion for IT, with you he is at sea….

    Warning, These tools can fail, and we experienced it during our crossing of the Atlantic, Always have your old sextant with you if you want to go to the end of the world. For me great weekend , and even in port we are already on the water on a boat. The magnificent cormorants are silent but present companions.
    Viel spass alle Leute ins Meer, and thank you for your interest to my husbands computering passion.

    1. Thank you Madam. !
      You practice, You understand, You appreciate… he's lucky Francis !
      For my own, I sailed that same weekend in the fog with Navionics on Ipad and InavX on Iphone (and the garmin 546 s of course !) The chart table PC with Maxsea often shuts down…
      Well, in pitch purée from the southern pass of the Gironde estuary, I was happy to check my position on 2 see 3 Independent systems !!
      But I wouldn't have an article in "boats" ! Sniff…

      PS : my friend had stayed by the fireside…she… re sniff…
