    Default Electronic Navigation backup alternatives

    Silver Alert, a Moore 24 is being outfitted for longer distances.

    Charting is covered by paper charts (full info with no zooming - yeah), Garmin Gpsmaps 742xs with all the N2000 network connectivity, and a handheld Garmin. Sailing will be in US as well as Canada.

    There othe additional digital devices that can be used as another backup, or as a standalone device on paddle craft. Here is what is available to use-

    Toshiba laptop running Windows Vista
    Acer Chrome
    Fire 7 or Fire HD10

    I have been uninvolved with any electronic navigation for the last 20 years. My question for the best alternative, if there is one, what are the general approaches to have an independent digital chart backup.

    As an aside, even though the N2K systems are supposed to all be compatible, with all parts from one source (Garmin) there is only one call for system troubleshooting.

    Thanks.

    We on Stink Eye use an iPad with inavx installed. We also used an Android tablet running OpenCPN (until it broke) Waterproof cases can be bought for both.
    OpenCPN is free. inavx is around $50.

    The Apple iPad can be an excellent low cost portable chart plotter. I have available at a reasonable price an Apple iPad2 (64MB, WiFi+ cellular model with built-in GPS) in Nuud (brand) waterproof case with charger and cables. Condition: Excellent, very clean, undamaged.

    Can run navigation apps such as Navionics or iNavX which uses free charts from NOAA.
    Price: $99.95 (less than the price of the WP case)

    Im using inavx on my iPad and iPhone, and an app from mapitech on the phone.
    The cellular version of the iPad 2 has built in gps so I use it without a sim card or cell service. I bought it specifically for additional nav.
    The only drawback is the screens not working with wet hands. Especially troublesome coming into Hanalei on a dark rainy night.

    When offshore ... You need maps locally. What do you guys do to have worldwide detailed and current charts?
    Outside of buying charts from Navionics I'm not aware of something else ....

    This is the great thing about OpenCPN. You can download the local charts for the region of interest. No cost.
