New Caledonia Maritime Charts

New Caledonia has excellent nautical charts and navigational markers.

With a few exceptions most of the marine charts for New Caledonia provide details suitable for shipping and larger vessels but when it comes to tight little remote anchorages that yachts will want to anchor in the details and dangers just are not there. Our Nautical Guide to New Caledonia lists all the French Hydrographic Charts for New Caledonia and you can buy these charts in Noumea or order them from most of the larger chart suppliers.

Makers of electronic charts - like Navionics, C-Map, and Garmin - have copied the details for their charts directly from existing marine charts. So they, too, often lack the kind of details in shallow water that yachts need to have for safe anchoring in remote areas.

Many boats are now supplementing their electronic charts with satellite views from Google Earth. This helps but there are, of course, no depths given in the Google Earth images and many areas have clouds hiding critical reefs and dangers. Google has also taken to erasing offshore reefs so you could easily get in trouble using these without proper charts or local knowledge.

Our cruising guide to New Caledonia will give you the kind of local knowledge and detail you need to assure you can navigate and anchor safely in New Caledonia. We personally have done the critical detailed hydrographic surveys using a GPS coupled depth sounder mounted in our dinghy and carefully plotting the depth contours and marking dangerous isolated coral heads. What you see on the guide is what you get when you arrive.

Let me give you some examples comparing the various charting options for New Caledonia.

Marine Charts and Electronic Charts for New Caledonia

Navigation along the west coast of Isle of Pines is complicated by a shallow area that has thousands of isolated coral reefs. If you don't have local knowledge you could quickly get into trouble here.

Without our guide your options to get to Gadgi are to go 46 nautical miles around the east side of Isle of Pines - often very rough waters, or make a 40 nautical mile detour west, out the turbulent Passe de Sarcelle and tack back into the SE winds to Gadji.

If your vessel draws less than 3 metres, our cruising guide will show you how to go from Kuto to Gadji in flat calm waters and the distance is 13 nautical miles.

Here is a comparison between charts for navigation of this area:

The Official Nautical Paper Chart

 

Using the official paper chart you would really put your vessel at risk attempting to pass through this area.

Not just because there are thousands of uncharted coral heads, but also because there can be a 2.5 to 3 knot current flowing past them and you need to know which direction the current is flowing and when.

Electronic Nautical Charts

 

This is what you will see on the latest electronic chart of the same area. The electronic chart makers don't come here to New Caledonia and do new surveys, they simply digitize existing charts - so you are not getting any more of the critical shallow water detail you need from the latest electronic charts.

With the level of information found on the electronic or paper charts you would be nuts to try this passage to gain access to the lovely cruising and diving areas along the NW coast of Isle of Pines.

Google Earth Images

Many yachts are now using Google Earth to provide actual images of the areas where the charts don't have enough detail.

But Google Earth does not provide any depth information and often there is surface glare or clouds obstructing critical dangers. Even worse Google has taken to erasing isolated reefs in many areas.

And of course you would still not know about the tidal currents. Believe me, if you were heading through this area with a 3 knot current in the same direction you were going it would be impossible to stop if you got into a tight spot.

 

Charts on the Rocket Nautical Guide to New Caledonia

Now THIS aerial photograph, route and depth information is good enough for you to navigate safely through this area. What you see here is a very reduced example of the extremely high resolution image you will see on your computer screen.

When you click on the magnifying glass icon on the menu bar you will see the individual coral heads and the depths between them. Like this:

The yellow line represents an actual track line of the Moira when we were doing the survey and you can load the complete route into your plotter or GPS right from the guide (Here is how to do it).

The depths on our guide are adjusted to mean low sea level and of course we provide you with the tide information for this area so you can plan your trip going against the current - thus giving you time to respond to signals from the person on the foredeck watching out ahead just in case you get off course.

You won't find this level of information any where else, and this is just one small example of how our guide will make your voyage to New Caledonia safer, easier and more fun.


Now lets look at an anchorage chart for New Caledonia.

The Baie de Oro is on the NE coast of the Isle of Pines and there are some interesting places to explore in this area, including nice beaches and the famous natural swimming pool (and some good restaurants too).

The official Paper Nautical Chart

 

One reason some anchorages are not properly surveyed is that they are too difficult for a survey vessel to get into to do the survey.

This particular anchorage was never properly surveyed.

No surprise here, if it wasn't surveyed to begin with the electronic chart does not have anything of value either.

Well, this is more like it. Sort of. Again you'll be hard pressed to know what you will find in the way of depths or suitable sandy areas to drop the hook. But it is a definite improvement over the paper chart.

 

Anchorage Charts on the Cruising Guide to New Caledonia

Yes, this is more like it. No clouds obscuring the image, a route in complete with waypoints, and there is that magnifying glass to zoom in to the critical area where you want to anchor.

These images are greatly reduced from the full screen images you will see on your computer so while they look OK here they will knock your socks off on a high resolution PC screen.

See that circle just above the 1km scale? That's a swinging room measuring tool. Click and drag it to where you think you want to anchor and you will see a 50 metre and 100 metre circle around that location.

What's more you can click on the information (i) icon and see details on what you will find ashore, mobile phone (and Internet) reception, TV reception, and whatever other information we could find when we visited the place.

Seeing your yacht on our maps

You can use any WiFi enabled tablet to see the high resolution images from the foredeck or cockpit. Here is how to set it up on your tablet.

That's good because it helps you navigate and see which coral heads are where as you are coming in to an anchorage..

You can't connect to a GPS and see your yacht on our guide. Our guide is not an electronic plotter.

Actually, our feeling is that you need to be looking for coral heads and dangers when navigating on this scale not navigating by GPS.

The GPS points we provide are extremely useful reference points and GPS is very accurate but when trying to stay on a route it is difficult to keep + or - 20 metres one side or the other.

So your eyes should primarily be on the immediate vicinity when you are coming into an anchorage with the guide as a quick reference as to what to expect.
