I will probably get shouted at for this but I find charts on a rib a complete PITA. So I dont bother. Instead I have a back up to the main plotter in the form of a Garmin handheld. Sealed in a peli case with some spare batteries. I then have my iphone with the Navionics App installed.

I don't & never have, carried paper charts on the boat. Unless you know where you are, they are pointless IMHO. I also carry a handheld Garmin (with Bluechart VEU706L loaded) & the Navionics app if it really goes tits up, & there's always the compass

I don't carry paper charts either. If I am on new ground I will copy small to carry in bag but I also always have Fly-to-me app on my iphone for back up.

Depends where you operate... but if there are objects you can recognise (marks, buildings on shore) its not hard to get your position.

Hmm, well an iphone and navionics seems like a cheaper option. Does a handheld Garmin simply have more reliable GPS reception, or is there any other reason that it is a better option than a phone & navionics?

Waterproof? No need to touch the screen with wet fingers to do things, longer battery life, cheaper if it goes for a swim, replaceable batteries...

Yup it's waterproof, has better battery life, more reliable GPS without the need for phone signal for improved accuracy.

Its easy enough to get a waterproof, floating iphone case though, I have one and its suprisingly good! The battery however I can imagine makes a big difference!

Are there any other features though, I'm just trying to justify to myself why I would buy one. Are the available charts more detailed for example?

Ah sorry replied before the second post there. Ok accuracy makes sense to me, if the Garmin is more reliable in that respect that justifies it on its own as I've had some very odd directions from my (admitedly old) iphone 3GS before!!!

Garmin not likely to be more accurate. BUT the iphone uses the phone mast to get a quicker first fix. If no mast it may take a while for first fix.

Missed - chargeable from 12V without compromising the waterproofing.

Waterproof box - you need to pick one that lets you still use the toluch screen..

The Garmin Etrex that I bought is still showing up on ebay. Its fine as a back up and you can get one for as little as £45.

I don't carry charts either; there's no point where I tend to go. I have a Garmin 78s as a back up but whilst it's waterproof and floats I'm not that impressed with it. It's ok I suppose but I prefer my Raymarine E70 screen.

Personally I preffer the Admiralty leisure charts, not on the rib though, just for home use, you can learn a lot by studying the contors and learning what all the symbols and abbreviations mean, that way you'll have more of an understanding of your plotter and the ground you cover and what to expect in any given erea. that way you can make on the spot navigation decisions at speed if necessary.
