We use paper charts as an overview for planning purposes. We rely on electronic for detail. Just purchased the charts and pilots we need to sail up to Orkney and then realised the space we need to store them

Aaaa totally confused didn’t expect you till Thursday. Now what do I watch with my coffee on Thursday. Great vid as usual. I have never used charts since Navionics brought out their electronic charts. ( many many years ago) I have charts and used some of them for decorations. Since Navionics I have used almost every new Navigation software brought on the market. My favourite is Orca which is free for computer, tablet, or phone. For course plotting on the day I still use Savy Navy which gives course to steer, takes into account weather, tides, and currents. Orca now does the same without the course to steer. Both Savy Navy and Orca are easy to use and read. I now find Navionics too cluttered and hard to read with all its colours. I have the Orca Tablet, IPad, and two Phones that runs all the safe software. If one goes the others are available. I have an eco potable power pack that I take with me everywhere. Sailing. It last about 4 days if solely used for charging all my kit. Main source of power is many USB ports for me and the crews electronics. As you mentioned with the current political climate there is always a risk of it being switched off which is why the Navy now use Quantum Navigation that can’t be tampered with. Will be a while before we can get it for leisure craft but believe it is on its way. Planes already have to divert around certain areas due to some nations messing about with gps signals. They are still making today maps we could use

We have Navionics, Cmaps on our chartplotters and Aqua Maps (core of Engineers) iPads/phones. NOAA stopped producing charts but you can now download them electronically and print them yourself. You are going to see a change in gps soon. They are updating how the gps get their time using atomic clocks so gps will be 1 more accurate and two less likely to be spoofed. In the US it would be impossible to keep paper charts for all the different inlets we move over 1000 miles twice a year to get out of the hurricane zone so we rely more and more on electronics to stay up todate. But the electronics companies are relying more and more on the sonar readings your ship provides for regions to keep well traveled areas up to date

I can recomend a Samsung T395. These are rugged and waterproof, and can be bought for about £100 on ebay or £195 from London Chart Plotters who sell them with Admiralty Charts loaded. I have two of these, both of which have Navionics loaded (a single licence can be used on two devices) and also have Admiralty and Anteres chartsloaded. Although they have a built in GPS, I feed GPS and AIS data to them over Wifi from two sources, and then still have the internal GPS as a backup. I keep them plugged in and charging, but the internal batteries work for several hours if necessary. I can tell you that they are really waterpoof as one of them is always out in the cockpit even in very heavy rain. These devices are our primary source of navigation at the moment as our ship is in Norway and paper charts are difficult and expensive there. Although I completely agree about getting a better overview from paper charts, I think we have to accept that their days are numbered and get on with it. A lot of rubbish is talked about losing all electric, but in out case I believe that the real risk is losing GPS signal because of jamming, in which case two things are needed; firstly to know that this has happened, secondly a good track showing where you have been (are now) on a plotter that can then be used in much the same way as a paper chart. I think there are still limitations in this regard with electronic charts but, on the other hand, the track logging is far more usueful than a traditional hourly log, provided you log all kinds of nmea data, not just position.

Samsung tablets – cheap as chips – all (even the small cheap ones) come with gps – for example ive just got 2 for £100 off market place – perfect condition – plus i have a ipad – 2 mobile phones and a laptop –
I like to think the world will sort itself out – and gps will always be available – -also news just in vodafone are launching a sat broadband service – like starlink – give it another few years these will be readily available and cheap – so you have backup broandband – finally services like navonics will allow you to download offline charts – so do that and if gps goes offline your still good to go !

This is so cool! We might not use it for now since were still rebuilding our 65' catamaran but definitely take notes for future reference.

My navigation system is an 11 inch tablet with GPS and WiFi etc. The battery lasts for about 9 hours, but I have a power bank that will charge it twice. So if the main battery system failed, I've got that backup ready. 11 inches isn't that big (!) but if you have a smart TV you can cast your android signal to the TV. So you could easily have a 26 or 36 inch TV which could act as a display when passage planning. Must admit I hate the endless scrolling and pinching on screens to get into the detail, but it won't be long before the electronics does all of the passage planning for you, and you just follow it. Good thing? Or a bad thing?

I have a mix of Admiralty and Imray charts and like to have an appropriate one, along with the accompanying pilot book, for everywhere I go (mainly West Coast of Scotland, East Coast of Ireland and the Irish Sea. Although I have a chart plotter by the chart table and another by the helm, an iPad and iPhone, all with Navionics, like you I prefer passage planning on the paper charts. I also plot our position every hour on the chart (and enter it in the log). We do quite a lot of night sailing and apart from the safety angle, it’s a reassuring way of gauging progress – or lack of it. I once lost all electronics on passage (before I had phone/iPad backup) and was hugely grateful for the charts, compass, record in the log and dead reckoning…….Thanks for the way you present and discuss this sort of issue which is highly relevant in these troubled times.

I have installed OpenCPN on a small PC connected to a TV/monitor on a swing-arm-mount on the chart table. This is where passage plans/routes are made. I also have AIS and radar as overlay here. I have a 9” MFD/chart plotter at the helm station with Navionic charts. On my Ipad I have Navionics charts and an app to mirror and operate the MFD from anywhere on the boat. I have a few rolled up passage charts clipped to the inside of the saloon roof, but they are not used anymore. Few years ago, off the German north sea coast we experienced GPS spoofing that set us off more than one nm from the correct position.
And that happened on all our electronic chart systems. Scary as we were in shallow water… aproaching the Eider canal. I also had Navionics on my Android phone, and it showed us to be in the correct position. The positioning on the phone is done by GPS and by triangulating cellphone base stations. In our case this served as a “correction signal”.
