iPadNav.fr becomes iTabNav.fr

Posted on25 June 20148 th 20242 comments

March, the 14 th 2011 I had announce the opening of an e-commerce website focused in accessories, mounts and connexion devices dedicated to iPhone and iPad for marine navigation : iPadNav.fr. Since then, its founder and I maintained a close collaboration, our complementary actions allowing us to provide an effective response to all new users of these wonderful tools perfectly suited to nautical activities. Many of you were able to meet me several times on his stand, both the Grand Pavois de La Rochelle and the Paris Nautic boat show.

After three years of existence, Dominique Gauthier company has grown considerably, to the point of wanting to expand its offering to users other than boating : outdoor sports, hiking, trekking, fitness, and all leisure activities for which numerous targeted applications are now available, both for Apple devices and for the fast-growing market for Android devices.

Thus, iPadNav has just announced in a press release the change of name of its website to iTabNav.fr July 1st 2014, in a desire to open his offers to all useful accessories for tablets and smartphones, regardless of brand or operating system, and for all leisure activities.

Hope that this new extended offering meet the same success as for leisure boating and sailing, because iTabNav.fr will offer specialized products scattered across multiple foreign websites on a single French website. With local French service and support as a bonus.

Already lived in 2011 during a stay in La Reunion (²), this time back from a recent trip to London I brought back the "proofs" below, screenshoted aboard an Airbus A320 : Read more …

Electronic charts : scales and overscale [Update]

Posted on6 May 201420 July 2020

A recent email exchange with a Mediterranean user drew my attention to a specific aspect of electronic charting : zoom limitation of a chart. ENC vector charts (¹) are classified in 6 categories depending scale : smallest scales less than 1:1.500.000 for global views to largest scale up to 1:4.000 for harbours and anchorages. (²).

Marine charts international classification

In most cases, ENC S-57 (¹) official charts the most detailed have a scale about 1:4000, thus 1 cm on the chart (screen view) represent 40 meters on the ground. With paper chart, the only way to get more details is… to use a a magnifying glass, that provides, as we know, in no case more accuracy. But it is quite otherwise for electronics charts.

Apps de navigation : the (rares) new products in Spring 2014

Posted on28 th 20145 th 20245 comments

The least I can say, it’s that the new things don’t jostle. After the frenzy of announcements of 2013, the developers seem to be marking time. It is likely that the proliferation of navigation apps should not promote their profitability, and that the financial return on investment in development and maintenance time should not be obtained by everyone. Navionics charts remains the undisputed leader. By creating its new “Boating” formula to complement and/or replace “Marine” (¹) it revives sales which were probably starting to run out of steam. iNavX remains the best-selling independent application in the USA, and the rest of the world through combination with Navionics cartography, and particularly in France thanks… to the strong promotion to which I contribute. Its developer multiplies very regular updates, which ensures good positioning on the AppStore and user satisfaction, despite the questionable ergonomics of certain functions. Read more …

ZenLoch, The boat loch of the 3rd millennium

Posted on1 th 201428 th 20218 comments

After the sextant of the future (¹), presented at the Paris Boat Show last December, here is the loch of the future revisited by a "Professor Calculus", an electronics engineer and genius inventor from Nantes.

The oldest among us will certainly remember this venerable and inexpensive instrument of the old sailing navy : The "boat loch". Quote (²):

The "boat" is a wooden plank, weighted to float vertically and connected to the log line by a crow's foot. On the line we tie knots, spaced in principle 7m72 (or 1/240th of a nautical mile). We put the "boat" in the water and let the line go. we then count, from the first node, how many knots pass through the hand in 15 seconds, which gives the speed in knots.
