Electronic Chart Sea of Cortez

[Exmoor]

I have a Raymarine A65 GPS Plotter

And need a chip to cover Sea of Cortez

Would I be correct in thinking that a Navionics Gold would be the best option?

All comments welcome

Since all comments are welcome...

We had electronic charts in SoC and they were all routinely off by as much as a mile. The only thing we ever used our chartplotter for was to enter waypoints from The Sea of Cortez guidebook into.



This was a shot of us sailing off Isla Espiritu Santo in 125 feet of water.

Agreed. Have traveled down the coasts of western baja and up into the Sea of Cortez and can verify as well that we have anchored as much as a mile and a half in from the shore line and sailed right over a couple of islands according to our GPS. Not saying the GPS positions are wrong... it's just those charts from the late1800's lying underneath your lat./ long. positions need to moved over a little. Never go in anywhere at night. Ever.

When you see straight lines and square (or nearly so) corners for a land mass then you should immediately become suspicious and compare to a paper chart. It should be plenty obvious that the electronic chart does not have resolution suitable for near shore navigation. If no paper charts are available next best is to check with one of the Internet based satellite image sites. There is no reason to fear electronic charts if you know their limitations before setting out. If yours are low resolution then paper will be mandatory.

Why not use a combination of CM93 and Google Earth?
GE2KAP easily creates a navigable .kap chart.

Here a screenshot from Marine Navigator.

If you at the same time also create a navigable chart from Google Earth alone in the same scale,you will be able to ´see´ the shallow waters.

See if somebody near ya has some Mexican Navy charts for the sea of cortez! they would be the best ya can find for there ! I don't have them, but have them for the gulf side, and was told they are available for the Sea! Just a thought ! and I would love some myself !!
