Re: Best electronic Charts for...

I used the android 7compression utility plugin for es-Explorer to extract.

Are you sure you downloaded fully before trying to extract?

Btw. As far as I know is Vaarweginformatie an official source. Nothing dubious at all.

I think this is not a problem on YOUR computer. I think it is a (temp?) problem on the server. Normally it works correctly on my computer but now I got the same message.

I will report later.

Re: Best electronic Charts for...

Now that was a rather usefull thread already.
The one thing I didn't come across yet it a source for charts from Thailand... any ideas there? Right now mostly for the sail from Ranong to Phuket but later in the season also further north towards Burma...

Buy S63 through O-charts or see if the china website where you login still has free updates.

Note also that the last version of CM93 is missing some of the detail of the next to last (don't ask me which ones these are).

Lastly, keep in mind that these are NOT FOR NAVIGATION. They are not up to date, not official, not legal, pirated charts. I emphasize: they are NOT UP TO DATE. Use them only for basic planning, if you use them at all (many people will say it's not moral -- you have to make up your own mind -- and in any case at your own risk and on your own conscience).

Then, buy up-to-date licensed charts from Jeppesen (the owner of the CM93 sets) for those areas where you will actually be.

Put those in your chart plotter, maybe, and use O on a laptop for planning and/or nav table use.


It is not responsible to sail without updated, official cartography of some kind. If you run into an obstacle which is shown on updated charts, because it's not shown on whatever chart you have, it is all your fault.
Sorry, I would not have expressed this that way:

1. Once upon a time they have been made vor Navigation
2. Chart offsets google for, but mostly your eyeball is enough (before dark)
3. The new Jeppensen vor small boats are nothing better than the old and yes I do have them, believe it or not, some CM93 versions are much more usefull than the Plan2Nav now
4. Yes the newer the version the less information, but sometimes the more accurate. But for example, a countainer port since >10 years is in use, but not in the newest chart, at least in the old as reclamation area, what do you think of that, Skipper goes into prison not using the newest chart, but the chart companies do not care, if they do not and sell wrong charts...
At least Navionics is closer up, but agaiin, many small bays are just greyed out, in the old CM, misplaced but there, are the depths.
5. Set aside a few earthquakes, how many miles do islands, bays rocks wander every year? And an official chart purchased for the Red Sea dated back when Negrelli had surveyed that area with help of the Austrian Navy when he started bulding the Suez Canal, after his death the canal was finished by British. Now this is a NEW chart!

I sail with the newest charts from Navionics installed and Jeppensen Plan2Nav on Tablet for chart checking, but always keep an eye on openCPN development, did not find more mistakes in CM93 than in the newer counterparts, but compare and use not only one issue, 2002, 06, 07, 09, 10, 11 i know exist. May 09 might be the best balanced edition, most positions are quite correct, the 06 edition seems to be the most complete one, least grey areas, but easily puts you on a rock, at least you know how deep. And you can easily correct for the offset. I cruise Far East

I do not disagree with any of these remarks, which could be equally said about the Baltic. Not more mistakes than other charts. It's extremely useful to have multiple cartography on board, as if two charts don't agree, it's a warning to be alert. Of course in the Baltic, you may have even three charts agreeing about safe water somewhere, which turns out in reality to be a rock . Don't ask me how I know

My remarks were meant to warn sailors not to use these as their only or primary charts. Their being that much out of date, is quite enough reason to say that. For navigation, use cartography which as been recently updated.
