Tablet on a boat? again!!!!!

At the moment we use Memory Map (£25) on the PC and download the selection of charts that I need depending on where we are going. With a 16gb iPad we have no problems with downloading all the charts for the west coast. I chose the MM charts because the one license covers 5 devices so I can use on the PC, iPad etc. great for planning at home. I also still like the look and use if individual charts on the iPad with very easy movement between charts.

As to the charger, this is the one I use, http://www.amazon.co.uk/Belkin-Char...8029&sr=1-2-spell&keywords=Belkn+iPad+charger

Happy to show you what we have and use next time we're up in the next week or two.
 
I agree with you that the galaxy not 8 is realy good. However i would point out one very important thing to youas i do to all my students. If you wish to use electronic devices for navigation then only buy a dedicated device. There are many on the market. We have been using garmin for many years and have just updated our chart plotter to a garmin 750 touch screen which is realy good. Tablets have their places on a boat but not to rely on for navigation.

Where did I suggest that a plotter is essential?

Isn't it implicit in the suggestion that a tablet is no substitute? If you mean "not exactly the same as" then of course you're right, but plenty of us find that sheets of paper make perfectly acceptable substitutes for a plotter, so I don't see why a tablet shouldn't count to. In fact, since tablets are much cheaper, more portable and do many, many more things, it might be more credible to claim that a plotter is no substitute for a tablet ...

Why would a tablet with a full set of UKHO charts be worse than a plotter?

Just keep on digging, again.

FYI Tablets and Plotters are different animals. Tablets can do things that Plotters can't. Equally, Plotters can do things that Tablets can't. Therefore they are not substitutes for each other. Neither of them is essential on a boat. OK?

Once you say that nothing can be a substitute for anything different, you are saying that nothing can be a substitute for anything else. Which may be true, but is pretty trivial.

And also a fallacy, since you most certainly can substitute a plotter with a tablet. Take the plotter out, put the tablet it and bingo! you've done it. You gain some capabilities and you lose a few. Perhaps you meant "complete replacement"?

Just keep digging, you're nearly at the bottom now.
 
Great plan. For what it is worth I find the Navionics app (with seamless vector charts) much easier to use than phaffing around with MemoryMap and its use of discrete raster charts, for general usage
On the other hand The Antares Charts are fantastic for the detail of selected anchorages etc.

Agree, the MM charts just don't work as well but adding the Antaries charts makes them worthwhile.

What is it that a Plotter can do that a Tablet can't?

I'm sure you know the answers already, but apart from the obvious, how about being waterproof, and being able to be seen in sunlight?

lifeproof case, tilt it a little. Neither of these perceived deficiencies hold true. How do I know? I used one on a 1200nm trip from the Algarve to Azores.
 
I don't really need to be warned about depending on a tablet, for a start the tablet is my wifes and as the Op I indicated that she was likely to have it aboard so I seemed reasonable to make use of it.
For what it is worth I do most of the navigation using a Dell 17" laptop running Seatrek with a full UK set of Admiralty charts,tidal streams etc. The laptop is recharged from a 12/19v transformer and sits on the chart table which is big enough to allow a once folded full paper chart to sit beside it with a Yeoman pad and cursor. To be honest I now never go to the bother of indexing the Yeoman though if visibilty is poor I will pencil the time and position on the paper charts from time to time to cover against a total electrical failure. Above the chart table is Philips Navigator with a separate Gps receiver on the pulpit, it gives course and speed and the position to the DSC VHF powered by the boats 12v system (3 batteries) so that is more back up.
A friendly forumite called this morning to drop off a free aerosol of contact adhesive for my lining problem (separate thread) and when he was here he showed me his Ipad with Admiralty and Antares charts running together on Memory Map, very impressed, amazing detail on the Antares anchorage detail but also I was impressed by how the Memory Map software overcomes the pre historic Admiralty indexing system and integrates all the available detail for any location from any source on one page, another advantage was that MM allows up to five copies to be used meaning that all devices can share.
So I will buy a 2w.+ 12v charger for the tablet , and definitely invest a tenner on Antares detail, I could use my second permitted copy of Seatrek on the tablet to avoid paying again for the Admiralty charts but I will be very tempted to switch to Memory Map particularly because while Antares list quit a few compatible options including Seatrek they strongly prefer MM. Problem is I have got used to getting my tidal heights and streams without ever having to count.

I used one of these http://www.voltaicsystems.com/fuse10w.shtmlWhich gave my iPad total autonomy from the boats systems. Shame Mr Redford didn't have one on his recent sailing trip. It would have saved him learning to use a sextant in his liferaft ;-)
