backup Chartplotter?

[vandy]

Hi, I am thinking of purchasing a standalone (built in GPS Antenna) Chartplotter just in case the main plotter fails as we plan a for a slightly longer cruise at the end of September...

I have seen Standard Horizon does the spec I want, but has anyone tried any other brand? Any advice?

One option is to get an iPad with the navionics app and a waterproof case. Very good as a back up and has many other uses as well...

Enen navionics on an iPhone is so accurate ( most of the time) it is astonishing. You can see which berth you are in! Cost about £5 when I got it but I think it has now gone up.

I've got two fixed sets (Raymarine - one on the flybridge and one lower helm) but most importantly an eTrex handheld job in the grab bag. If I'm in the literaft I really, really, really want to know where I am!!

Internal batts also offer total independence from boat electrics in case of catastrophic electrical failure.

good call.. we have an Etrex with chartplotter software loaded but it's stayed in a cupboard for the last two years with the clip in stand on the helm... purely as a backup in case we lose the main plotter..... it should be in the grab bag not the cupboard

We have I phone app & a back up handheld in grab bag as above. Recently upgraded our main Raymarine Navionics charts for the UK. Does the I phone stay up to date automatically, or do I need to give them more money for an updated app ?

Any decent waterproof hand held that uses AA batteries.

Charts make good back-up: - you know, those paper things that look like maps.

Sadly it seems paper charts are becoming a thing of the past. Modern electronics have proven reliable and with separate redundant systems one will still be able to navigate if one nav system fails. Radar and AIS are another means of position fixing should gps with eyes and sounder as last line of defence. Paper not needed as even if gps signal is jammed the chart will still display on a plotter for manual fixes (ie HBC, Radar, etc)

If you want a fixed chart plotter, the Garmin GPSMap 551 is a better buy than the SH CP180. Fully stand alone and includes charts.

The handheld GPS is another good backup, as mentioned.

And a paper chart is b***er all use in a liferaft.

Also pretty useless if you don't know where you are. We do carry paper charts and a handheld compass and i could get home using them, if i could work out where i was. If it was foggy or there was no land in sight i'd be knackered though.

First line of defence if the plotter fails is a laptop, to which i can connect a Garmin Etrex. Next line of defence would be using the handheld with the paper chart. After that, i give up, someone above has it in for me and i guess my tme is up
