Ahem, 'dead reckoning' please. Sorry.
Paper charts can provide a wider perspective/view.
My wife is watching a trawler journey documentary. The yacht has every electronic navigation aid imaginable but still uses paper charts as well. She asked why they would use paper charts too and I didn't have a good answer.
Can you help educate her and myself as well.
I like raster over vector...but that's just me...it has it's limitations too just like some vector charts. No increased situational awareness for me at least.
For those that keep saying they are different....how is a raster chart on a screen any different than a paper chart? It's basically just a photo of it.
I prefer raster, too.
FWIW, I think when some say they dislike or have trouble with "electronic" charts they really mean vector charts.
Our previous MFD (Furuno NN3D, now kinda old) served up either or both. The current (Garmin) only does vector...

Okay, so you lost all your 12vt power and your navigation displays go dark.
Oh did I mention you are out of WiFi and cellular range? Assuming you knew your position 15 minutes ago.... a paper chart and a good compass would be nice.
========================I hate to use the words I want too.... so I won't.
Dan...electronic charts can be downloaded on a electronic card and can be reloaded on any device capable of accepting them...In my case with a passenger aboard that is 2 phones, 2 pads and 4 laptops.
Maybe crossing an ocean I could theoretically lose all... but I bet I could get one charged and good enough to make landfall....but I have a bigger chance of getting hit by a meteor than having to go through all that.
You have NO idea as to what is going on with electronic nav and I am sorry to have to point that out.
Ai any time I can plot a fix on an electronic device and some will nicely DR for me. I don't have to have GPS to get a fix necessarily and plotting a fix on an electronic chart is just about or as easy as a paper chart.
I cannot for the life of me figure out how people do not know that.
I have only had GPS go down once on the last day of an Australia to NZ trip. Let me tell you that it is no fun approaching Farewell Spit at 3am without positioning. I have also had one lightning side swipe that took out the GPS, and one that didn't.

Granted, some paper gives info that the electronic charts don't have, but Google maps is for that.... WAY more info that a paper chart.
I have been using plotting software on a 14-16 inch laptop that is more than adequate for the nav that I do. Not sure why you think a raster chart from NOAA isn't available on a 14 inch laptop...I have been using them for a decade. You can zoom in on a raster with great definition where a large marina fills the whole screen

Apparently you did not read my post for comprehension. Of course raster charts are available on electronic displays. Go back and read again - your visibility into that raster chart is either a miniature version of the whole, or a small part of it. It's like going to the Sistine Chapel and only being allowed to look at a postcard of it, or view through binoculars one tiny part at a time. You can claim to have seen it, but not the same experience at all.
It is surprising how little a coastline changes in many decades. Nav aids change, though usually slowly, but rocks take a very long time. And in any case, electronically distributed raster charts are updated, usually monthly.
I have seen lightening take out every single electronic device on a boat, as well as many of the switches and motors. Your 2 phones, 2 pads, and 4 laptops will be bricks. You are far more likely to be hit by lightening than a meteor - it is actually a fairly common insurance claim, even in coastal and inland waters. The claim often involves replacing all the electronics on board.
You can navigate effectively with raster, vector, paper, or electronic means. It is quite ignorant to say that there are not both advantages and disadvantages to each of those methods. An individual chooses what works most effectively for them. That does not mean their choice is best for everyone.

This has been a fun topic! The OP simply asked the function of paper charts to explain to his wife why an electronically equipped trawler she was following online was using them. A question which he was not able to answer.
A number of fine people dived in and provided reasons why someone might use or just have on board a paper chart even though having electronic plotters available.
That was a perfectly adequate answer to the OPs question.
It is unclear to my why a number of other fine people waged in on why paper charts are completely unnecessary, extolling all the advantages of chartplotters and one even calling those using them luddites etc. The perils of answering innocent questions!

LOL Spell checker plus some keys no longer work on y laptop.
For all who like paper charts, more power to you. Nothing wrong with liking them or having them. Just stop implying that somehow your seamanship is better because you have them. Just leave it simple as "I like them and I'm more comfortable having them along."
I've not implied that, but I have objected to particular posts which flat out state that those using paper charts must be ignorant of electronic charting equipment and methods. It is actually great familiarity with them that makes one appreciate the advantages that paper charts have. And they do still have some. Maybe not compelling advantages to a particular individual, but that does not make everyone else ignorant.
Also, using an electronic calculator to do your sight reduction is kinda cheating, isn't it?
Yet in the 100s (1000s?) Of posts I've read, I don't recall anyone relating a credible actual story of needing, having, and using paper charts for navigation when electronics failed. Versus phone, tsblet, or PC navigation options
