Free Worldwide Jeppesen Charts Online

Some buoyage is depicted if you zoom in close enough but it's patchy ... aha, if you go to the top right of the chart and click on the 'Charts' button and select full suddenly all the missing detail appears

I think they are raster tiles at three different levels of detail derived from a vector chart source. Ah, I see Jeppeson do a range of C-Map charts so that'll be the source data then

There's a lack of info on how up to date the charts are so I wouldn't trust 'em for nav

The AIS info looks to have the best coverage of any on-line service I've seen (yeah, I'm the sort of sad barsteward that can spend hours gazing at symbols moving around the laptop screen!) - pity it costs $1,800 a year to get real time info though :eek:

I was initially concerned that some rocks appeared to be missing, but having selected "full" everything seems to be there - brilliant.

I suspect that it's fairly well updated, too, if they're working off the Jeppeson masters. A couple of checks of recent buoyage changes, e.g. Ardluing S Cardinal (installed a few months ago) shows them correctly depicted, but the new light at Branra (a few weeks old) is not shown.

This could be a very useful home reference, especially when the charts are on the boat.

The Eastoke Bouy at Chi is there and that's not made it onto my recently updated & paid for Navionics app yet, so apparently fairly up to date.

Daydreaming at home/work has just got even better. :-)

Having compared these with the real thing there is still a lot of detail missing after all for this website would you buy the full package or a cheaper cut down version that is not really suitable for navigation

I somehow doubt they had on-the-water real time navigation in mind when they chose it. :D :D :D

Can you give an example of some missing detail?

Why not check it yourself, you always seem to be tryiong to get others to do the work for you

I've had a good look now and I can't find anything too outlandish (I've looked at a few obscure spots in Scotland and around the South Coast).

You clearly found at least one bit of missing detail, I'm just interested in where it is. It doesn't seem an unreasonable request.

For a start there is no details of any light characteristics at all, of course not really required to see AIS data but I have always found things like that usefull for navigating, strange I know. I also found it easy to find chunks where the chart data was limited compared to real charts. Now it's your choice what you play with, but that little source of chart info is not on my list.

Good that's one. Missing object info. (I'm not convinced that anyone other than you is evaluating this as a tool they'd use on board for on-the-water real time navigation but even so that's certainly some missing detail in the conversion from vector to raster.)

Example? I don't doubt they exist, I just want to take a look at a 'bad' area and so far I can't find anywhere that's too bad. Why are you being so evasive, these aren't difficult questions. You could have answered this stuff in 5 words ages ago.
 
I reckon it's fantastic for checking anywhere in the world for whatever reason one might like.

For me, I was reading the Patrick O'brien novel "The Mauritius Command" recently.

The description of a naval attack on the south-east corner of Mauritius depended heavily on an understanding of the geography (marinography?) of the place.

I spent a couple of hours getting a rather vague idea from google maps.

A few clicks on Jeppeson charts put me right in the picture. Speaking of which, a double click to centre then zoom down seems to work accurately almost every time, which is not the case with google.

A wonderful aid for armchair cruising.

It is true that most of the light characteristics are missing, but colour(s) and sectors are shown. I think (from memory) that this is consistent with the normal C-map display. I have C-map on my chart plotter and I think that to get the other light characteristics it is necessary to click on the symbol which then shows all the data in a box. (The same applies to finding out the depth of isolated underwater rocks: they have an annoying habit of showing rocks which, when clicked on, prove to be 50m or more down. This has led to a few unnecessary panics.)

I would be interested in any other examples you have spotted.

For the avoidance of doubt I was not considering using this for navigation, but as a useful piece of home reference material.
 
looks pretty good, tho can't seem to be able to right click on items eg rocks/lights to get further info. zooming in, seems same level of detail as admiralty charts (and same errors!)

thanks!
