Frinstance... on any day of the week there are between one and two dozen ships anchored off La Plata... on google earth...?... nada!

Any sign of the dredged channels into the Parana or the Uruguay?... nada!

The water is shown as blue... the waters of the Rio de la Plata haven't been blue in a million years... its brown....

GE is wonderful ashore.. I recently used it to measure the height of a tree at Campo de la Ping...

Afloat? Not worth a penny's worth of penguin poo .. imho... ymmv...e&oe ...etc
You may want to use the dated 'archive' views from the display menu (sorry, back translated from my French version).
I got those ships off La Plata

I don't understand why not? One of the major benefits of GE chart overlays is in correcting the land position inaccuracies of the "official marine charts" in many places.

The color of the water or presence of other boats is inconsequential here - and most overlays are done with a transparency that allows the chart's depth and water datum to show through.

That alone makes it worth a lot of penguin poo to me.

I wouldn't put too much faith in either the marine chart or GE being correct. The combination of aspect ratio, scaling, and registration of images on the geo frame seems at best to be an art, not a science. Eyeballs are probably the most trustworthy!

Although, I'll admit, GE is closer than any marine chart in the areas I frequent.

Re: Poor customer service by Maxsea and C-Map, or don't sail to Easter Island

FYI I do have cm93 etc as a backup. I just feel thatMaxsea could have easily remedied this issue and chose not to . They should suffer the social media consequences. I'll let you know if we find Easter Island in a month or so. We did stumble into San Cristobal, Galapagos last week.

Re: Poor customer service by Maxsea and C-Map, or don't sail to Easter Island

Hi Paul, Easter Island was one of my fave landfalls of all time. We had a hard beat down, as close hauled as our old Herrshoff would pinch, plowing into 6-8 foot seas for 10 or more days, but still worth it. We were into wind as soon as we left Isla Isabella. We were late though, into April.
We were treated very well and were delighted to find fantastic provisions, New Zealand lamb, turkey and good vegies. Of course the good Chilean wines were enjoyed as well.
Incidentally, it is the only country I have ever cleared out of where the port captain wanted to see that I had charts for our next intended landfall. They also called us many times to make sure we were aware of any weather concerns.
We spent two weeks there and only were blown out of one anchorage by clocking winds.
Regards, Greg

Re: Poor customer service by Maxsea and C-Map, or don't sail to Easter Island

Paul?
How do you feel about lobbing grenades?


Send a paper letter (better) or email to the Chilean State Department or some other carefully chosen agency, to inform them that Maxsea does not recognize their sovereignty over Easter Island, intentionally omitting it from their maps of Chile.


Carbon copy the letter to Maxsea.


One never knows...some governments are awfully touchy about these things.

Re: Poor customer service by Maxsea and C-Map, or don't sail to Easter Island

Paul, Are you turning left or right after Easter Island?

If heading to Chile proper check you Maxsea charts for the waters south of Golfo de Penas against your CM93 ones running under OpenCPN. I will be very surprised if there is any difference between the two. Last time I looked at Maxsea on another boat they were identical but that was a few years ago.

Which means that they are quite basic and have significant errors in longitude in many areas .
Most people just buy the big Chilean Chart Atlas - 'Atlas Hidrográfico de Chile' - Servicio Hidrográfico Oceanográfico de la Armada de Chile which has every Chilean chart in it at a reduced scale, make sure you have a good magnifying glass.

SHOA put out electronic charts but they are not cheap. Servicio Hidrográfico Oceanográfico de la Armada de Chile

Left hand pic....openCPN at maximum magnification before getting the 'over zoom' warning.... right hand my BB display at 'best scale'. Area shown is south of Pto Eden... the CMap people probably just used the BA or US charts which aren't a lot of use in their paper form either....

I fail to see your point
The CM93 pic you show is at scale (about) 1/90 000. It is based on the Chilean chart (SHOA) 9000 at scale 1/500 000, which you show on your second pic, not on a US NGA or BA chart.
Now the CM93 chart at scale 1/500 000 looks (obviously) exactly the same as yours at the same scale...

My point is that, south of Golfo de Penas, CM93 charts should be used with great caution as in many areas they aren't much good, due to lack of detail and errors in longitude.
There are a few exceptions... around Paso Shoal they are OK and also through the guts of Magellan.

'Mariners be warned' etc.

I carry the Chilean Chart Atlas and a reasonably comprehensive set of original Chilean paper.... total investment about $400 maybe.

Re: Poor customer service by Maxsea and C-Map, or don't sail to Easter Island

Hi el Penguino.

I've just came north through the Chilean channels, actually in Puerto Aguirre now, and have been using Maxsea with jepperson charts and found them to be amazingly accurate. Much superior to the CM93 v2 that I have. My Jepperson charts are 2013 so quite up to date. Chile has released a lot of chart updates in the last few years.

To anybody else coming this way you need to buy the Chilean Chart atlas as el Penguino said, 70USD.

As for the whining about Easter Island not being on the packages from Maxsea. You can see that from the coverage information before you buy so all threats about them not delivering are hot air.

You could use opencpn and buy the s63 chart from chart world if you must have it.

Gday Chris, thats good to know... I may after all these years have to invest in some 'real' electronic charts.

So , speaking as the owner of the other one, you are actually at sea on that semi-derelict of yours.....? 'Her eastern side was chock-a-block with a mix of near-derelicts ....' Sequitur

My now not quite so semi-derelict goes back in the water in a few days

Cheers,
Ping

El P, and all,

I'll extract some screen shots Comparing the CM93 that I'm sure we all have with the Jepperson here in Chile. But actually uploading will probably have to wait till I'm at more internet capable destination

And yes she is not as derelict as she was and arguably not ready to go but sometimes you just have to go. Got quite a jobs list for Valdivia.

MaxSea Jeppesen C-Map 2013 and CM93 v2 2011 side by side

Area show in Angostura Inglesa, just north of Puerto Eden

Hopefully this upload works over my phone connection. Moving on in the morning so no internet for a while

Chris
