Further to my thread on electrical failure, everyone who replied said that they always sail with sufficient paper charts to navigate and pilot the waters in which they are sailing.
Does anyone here sail in unfamiliar waters without adequate paper charts and pilot information - i.e. does anyone here sail in unfamiliar waters relying on one or more electronic charting systems with no paper backup (which must, obviously, be fit for navigation or it is pointless carrying it)?
If so, can you tell us how you have arranged things so that you are happy with the overall reliability and risk of system failures due to faults in the units, or the boat's wiring?
I realise that this is written in a way that suggest that I don't think that electronics alone is sufficient. That is not my view. Given certain safeguards and redundancies (including some means of accessing the charts in the case of military interference with GPS) it would be fine to do so. I'd just like to hear how people arrange it to give adequate security.

Is there anyone here who sails without paper charts?
