Tablet chartplotting- not Navionics

I've been trialling OpenCPN alongside Navionics and have been really impressed so far.

One slight thing I've found the OpenCPN falls down where Navionics excels, is tidal (flow and height) data. Is there a OpenCPN plugin and data set which I can get for tidal data overlaid in OpenCPN to show the same functionality as Navionics?
 
i think they are raster charts, in which case do they cover the same level of detail as the UKHO ones in the more remote parts of the UK?
I think you need to ask a slightly more specific question. Unless he has a copy of both and did a full audit of them how could he possibly know?
 
I think that the website for VMH is bad for the same reason that the website of London Chartplotters is bad - the people running them are boaters first and foremost, providing a service that has a slim margin which leaves no money for modern whizzy website templates.
I agree that both are idiosyncratic but having dealt with them I can say that I've found them to be honest and the products remarkable for the tiny prices charged
I disagree. To create a simple web page/site is really easy, just needs a bit of thought and discipline. They have looked at it from the business point of view looking out not the customer's point of view looking in.
 
I use Memory Map with the UKHO raster charts, as has been mentioned all 800 odd charts for about £30. Also useful and fully integrated is that you can buy as a one off or annually, the OS 50k and 25k maps which is very useful when exploring ashore and for costal pilotage. Each license allows for use on 5 devices as well.

They cover all the areas covered by Imray charts at the same level of detail as Imray. And you get them free with our paper chart packs too.

Depends what you term as more remote. Some areas we only cover at passage scale but we've just released new coverage for the West Coast of Scotland, which contains more info than UKHO charts as it includes detail from Clyde Cruising Club books, for example. Do email support@imray.com with specific questions and we can let you know more.

There is the UKTides plugin, but I think it only does height.

I've had iSailor in mind as an alternative solution for places where official electronic charts get costly, and its tidal data appears to include both flow and height. (Their a la carte pricing model unfortunately adds up rather quickly.) The tides subscription is described as using the Simplified Harmonic Method of Tidal Predictions, as found in e.g. Admiralty Tide Tables. I've just briefly played with it and I like the ability to easily adjust the date and time displayed. Here is how it presents the data:

Are these raster or vector charts? And do you know the source of the chart data?
Clearly the accuracy and completeness of the chart data is crucial.

Yes they are c63 charts seem to draw quickly and since they are derived from mandatory carriage charts I have no doubts on the accuracy
 
The big plus for me is that Navionics is simple to install and use. It doesn't require any IT skills. When I first used it on my tiny Samsung mobile it cost £12 as a one off payment and free updates which has now morphed into about £30 pa which is not so good but still reasonable. Some of the other options have rather quirky presentation and no guarantee of accuracy (which must be the prime consideration).

I'm afraid that many posts on here have commented on the accuracy (or lack of it!) of Navionics charts! If you want the highest accuracy, you need a system that accepts charts supplied by Hydrographic Agencies; anything else is a derived product and has the potential for introducing error. I'm a (retired) map-maker who has been involved in checking Admiralty charts. And I won't use crowd-sourced chart data; there are too many ways it can go wrong, many of which have been reported here.
