Sorry if this is a brainless question but I have never used electronic charts, apart from a Navionics app on my Android phone - what is the usual process for keeping electronics charts on a chartplotter up to date?
 
Most these days have an application that you can download and then run the updates from your PC. However the updates are expensive. I can't say I update mine every year and I am sure that most do not.
 
Can you expand on this ie which ones are free?

I don't think any where you take it to a dealer are free. Did you misread pvb's post?

The new Navionics product (can't remember the name; you basically buy the card as an empty blank and download your chosen area of charting onto it via a computer) includes as many updates as you like for one year at no cost; after that you have to pay.

The electronic versions of Imray charts are available on an annual subscription basis and all updates are free. easily downloaded from the website.

I updated mine 2 years ago and was lucky enough to have a free update included in the purchase package. Cost last year for update to a C max card was quoted at £50.

Needless to say mine is now out of date again and annoyingly it does tell you everytime you turn it on, but I don't think the coastline has changed much since so not too worried.

Maybe more essential if you cruise hundreds of miles in different areas and of course buoyage has been known to change.

Every year! You could miss a lot of buoyage changes in that time. It's free with paper charts (well apart from the cost of a Rotring pen)

Quite.

If I had to guess the average age of electronic charts in use, I'd take a stab in the dark at five years or so. Some people conscientiously keep them up to date, but plenty of others never change the original cartridge they bought with the plotter.

I do keep my paper charts up to date.

Navionics is fairly straight forward and the instructions on the website are easy to follow. If your chip included one year free updates (as did mine), the year starts from when you register on the website, not when purchased. You could update every day, if you were so inclined.

After the first year, I don't know the price of subsequent years' subscription but I can't image I'll be saying "that was inexpensive, what a pleasant surprise"
 
Navionics give you a year of free updates following purchase - done on-line by plugging the chart chip into a PC loaded with the appropriate client software.

After your initial year is up, you can purchase further years of updates at a price that is rather lower than the cost of a new chip of the same type.
 
I took the view that the same update period was to be used for electronic charts as I used for paper charts.

In practice that means every other year but if we were going somewhere 'new' (i.e. waters we did not know to some degree) then we'd get an update, as well as new charts for the 'new' area. This year, that meant the Solent and Channel islands.

We had new charts (electronic) this year.

We plan to go back down the W coast of France next year, and at this moment, I feel I have no justification on lobbing out on new charts, either electronic or paper as the paper ones are still relevant from last year and the electronic are still 'young' enough.

On our last boat, we had C-Map. This boat has Raymarine and Navionics. The Raymarine kit is superior but I still prefer the C-Map charts. I think C-Map was a bit cheaper than Navionics

Surely the answer here is to just apply the paper-chart updates? Only cost is a couple of hours of your time; personally I rather enjoy it.

I've never sailed the west coast of France, but I remember from updating my big Western Channel passage chart that a number of large offshore buoys around the corner of Ushant were removed last winter (replaced with virtual AIS targets). You might get a surprise if you were planning to use them...

I must be either exceptionally conscientious or a bit of a twit then 'cos I religiously update my paper charts before every trip and now that I have the dubious pleasure of a proper chart plotter to play with too I do the same with that

Actually, updating the electronic charts is so easy that there's really no excuse for not doing it routinely before each trip. Updating the paper charts isn't much of a chore either when it's done regularly

I certainly wouldn't feel comfortable around the East Coast with out of date charts as there's almost always relevant bouyage or depth changes to make

Depends on the system you use. For some people it costs not-insignificant money to update, which seems like a reasonable excuse to me. Glad to see that things seem to be moving in the right direction though.

I can understand that in less dynamic areas of the coast / oceans even annual updates might not be entirely essential but to go even a year without updates around the Thames Estuary would leave me a nervous wreck! So since I've got to bite the bullet and pay the money to Navionics anyway I might as well update the charts regularly

Of course, that's fine with Navionics where it's an annual fee to have access to the update service as often as you like but things might be different if each update incurred individual charges!

Hmm so I am a bad buoy when my local chart is 10+ years old (uncorrected), and as I get further away my charts get newer but still not corrected?

Then again we sailed off the edge of our charts the other year!

Chart corrections to me are a bit like osmosis, as long as you are not stupid you might get embarrassed but should not come to harm...
