The barky has a C-MAP chart in the plotter which l am happy with.
I thought l am going to back it up with a tablet. Just because l can. Downloaded Plan2Nav - C-MAP's own Android app. - and from then on everything went pear shaped. It was very hard to register then the trial map-download was sluggish and slow. After three hours struggle l started plotting a route which was impossible to modify or re do.
In the mean time downloaded Navionics for a trial period and plotted and modified a route. No worries. They have a HELP file. C-MAP does not.
I like C-MAP because it is not a yearly renewable map download like Nav. but it is almost impossible to work. Sluggish, slow, non-responsive.

Did any of the esteemed members have any experience with C-MAP and Plan2Nav?
Am l doing something wrong?

I have C-Map and am happy with it. I can't comment on what you're trying to achieve because I wouldn't know.

I do like Navionics on my tablet too, but I have never tried to use C-Maps on it. All I do is work out where I want to go on the tablet at home. Then over a beer on the boat, I transfer the course (manually) onto the chart plotter. Not the most efficient way, but I enjoy it.

C-Map was the one used by the VOR yacht to run aground on a shoal off Africa, which was only visible if you zoomed in. Memory map sounds good, if a little expensive compared to Navionics.

Yes Ambler, thanks for your input, that was the reason l bought C-MAP, the chart datum based on WGS84.
I am a chart-person, l still use paper charts and when l bought my barky with a chart plotter but no card in it, l chose C-MAP on it's WGS84 merit after buying the paper charts of the east coast of Oz.
The progression from there was natural, first to learn how to use it?
The web site of the AHO is a permanent feature on my tablet.

Yarra, if one is not using the tools in his hands correctly, well, unfortunate it might be, but he can not blame the programs creator. Where were his paper charts when he run aground near Africa. Why he was not aware of the features of his plotter?

All ENC's are notorious of hiding datum on different layers of zooming. This was the first thing l ever learned about ENC's.

The reasons why l bother with C-MAP is, firstly, because l got one on the plotter which l like. Secondly, because l thought, if l could have the same charts on my tablet l could plot away from the yacht and - thirdly - use it as a back up while navigating. I have two GPS's on the boat, so l don't really need it on board.

I was - as l pointed out - after members experiences with C-MAP's android application called Plan2Nav?
I am not able to come to terms with it for either, my inability to operate it, or it's inherent problems. ln the mean time, l mastered basic Navionics - to prove to myself that l am not a total incompetent - while struggling with Plan2Nav and getting nowhere.
This is the peccant part, l would like to have some light shed on by someone with experience with the Plan2Nav application, if possible.

Thanks for the idea about MemoryMap. Point taken.
Also, l read the AHO web site extensively and the present standing on ENC's is very interesting. Please read it yourself, it is way too long and complicated to quote.
In the present in NSW, paper charts rule offshore!
(for small craft, that is! )

I was hoping to get plan2nav app on my samsung tab working too as I have Cmaps of the world. I couldn't get it to work so gave up. There is a Beta test of OpenCPN available for android that will run Cmap ecs. I guess the full app will be released soon.
My Aus NZ Navionics subscription just expired, I thought I had signed up for life until I ran the latest update. Ah well wont be renewing that! And I received no thanks for my contributions to them either.

All the best with what you decide fits your situation and budget.
cheers

Memory Map do zoom into the next scale chart. In fact if you are navigating on one chart and see a purple line or purple bordered box, it indicates there is another chart available within that purple border. You know to zoom in.
I haven't seen that feature on vector charts yet.

Sorry for the thread drift but I feel somehow responsible as a hydrographic surveyor (retired) if I don't point out pros and cons of different ecs. I hate hearing about situations that could have been avoided due to user error.

Vector charts won't show that there is a deeper layer until you zoom in to it, at least on the ones I have seen.

As a retired hydrographic surveyor please feel free to tip your brains out on the table here so we can pick through them.

It is unfortunate, that my original intention of asking about Jeppesens Plan2Nav android app.was misunderstood.
I got no intention to discuss charts at all.

To correct this l am starting a fresh thread.

I recently purchased Navionics HD for my iPad. The Au & NZ charts were $69.95 with a years worth of updates. I find the auto routing engine is pretty good although it doesn't like long passages (i.e. Sydney to Lord Howe island). The chart itself has lots of information, heaps more than my ancient paper charts.

Ambler, l am eternally grateful to you putting me on Memory Map!
It is the ducks guts, for me.
That was what l longed for. Thanks a lot.

I have cmap on my plotter (WGS84) and now l can have fun plotting to my lifes content on MM which is transferred to my paper charts. This way l am covered for most occasions reasonably cheaply and legally covered to boot.
Fair winds !
