I like alot of others have a stack of charts that you could borrow, just send a message,
No paper charts for one off trip

Perhaps when I used the word 'electronics' i could have been more precise. When we lost the gps signal in Naples the chart was displayed, only our position on it was lost. I tried our backup hand held gps, which also failed to give a position. Taking our last known position from the log, about half an hour previous, I was able to mark it with a waypoint. The plotter was able to tell me the bearing from it to the next waypoint at the south of the bay.
If the plotter failed completely we would have the chart stored on the laptop, and nowadays the iPad.
Re the lost gps signal. Shortly afterwards one of the mags issued a request for people who found areas where this occurred to contact a researcher into them. I did so and he advised that the Bay of Naples was a well known one, attributed to strong electrical or radio emissions from the US navy base there.

If you take the trouble to read the thread you will see that someone said that if all electronics failed and you had no chart then you could rely on "traditional navigation" if you can explain to me how you Navigate without any form of chart or instruments then I shall go on a course to learn myself as clearly my Yachtmaster Ocean and Instrument Rating have left me navigationally challenged..
The Polynesians and Vikings certainly navigated. Every civilisation that didn't have paper must have managed. So simply get books about their methods.
Might be a bit risky and time consuming by modern standards though.

I have read several, especially "We the Navigators" http://www.amazon.co.uk/We-Navigators-Ancient-Landfinding-Pacific/dp/0824815823 which I was actually referring to In post #38. Please try to keep up.
This matter has all been cleared up rather nicely by Vyv. He wasn't suggesting navigation without any paper or any electronics.

If you have no chart at all, of any scale, and all your electronics fail then all you can hope to do is somehow find a safe way somewhere. Not necessarily where you were going to or came from. Just somewhere. That's not Navigating.

I think we have reached the stage where many boats can manage safely and reasonably without paper charts.
It is an area which is changing rapidly.
When I started full time crusing about 5 years ago I had one set of electronic charts and carried paper as a back up.
I now have detailed electronic charts on 7 separate devices.
I think this is enough redundancy and paper charts are no longer necessary.
Pilot books of any unfamilar area a great help and are always carried if available, but i think it wont be long before these are electronic as well.

I think you are right. After all, an iPad with no GPS signal if effectively just a paper chart on a screen.
With the chances of losing absolutely everything electronic, which is probably only possible with a lightning strike, perhaps we shold just accept that if it happens our number truly is up.

That was kind of my point. Jimi didn't ask if he would still be able to finish his trip without the paper but rather whether he'd be in trouble if all of the kit failed and the answer is a definite "no".

Thank you. I love your reply. Perhaps you have missed the point. We are not discussing being safe. We are discussing navigating. If you want to be safe then just stay where you are!
Sorry, but I do have spare charts (and they are laminated so they can get wet) a watch and a sextant. I also hardly ever use them as my two plotters, 2 gps aerials, 2 iPads, 2 iPhones, a MacBook, PC with GPS dongle are more than up to the job.
But that is missing the point, and neither am I insisting that anyone carries anything.
My point is a very simple one. If you have no chart at all, of any scale, and all your electronics fail then all you can hope to do is somehow find a safe way somewhere. Not necessarily where you were going to or came from. Just somewhere. That's not Navigating.

You must have a very large boat
And a lot of patience to wind a watch every day on the off chance that judgement day arrives!Ex-SolentBoy

If your boat is big enough the crew deal with things like watch winding.
