Seatalk NG to Boat 4G router to Navionics

[MagicalArmchair]

Mirage has a Raymarine e7, integrated to radar and the AIS 700 unit I fitted (it even works!) at the end of last year, down below at the chart table. Although I have still to go sailing on my new boat (for one reason or another!!), I have looked at the Raymarine app for the iPad Pro I'll be using in the cockpit, and whilst its a good concept and gives full access to stuff like the radar, I do much prefer the Navionics app. With this in mind, I want to get the following set up:

1. A SeatalkNG to Wi-fi bridge (one of these (Yacht Devices Wi-Fi Gateway for NMEA2000 / SeaTalk NG YDWG-02 (Seatalk NG): Amazon.co.uk: Sports & Outdoors))
2. A 4G router so that the iPad can still access the internet as well as the Seatalk data
   1. Something like this? =>https://www.amazon.co.uk/dp/B073RNXCHK/ref=cm_sw_r_cp_tai_h4NTEbM076Z14<=
   2. Or something with an external 4G aerial like this that I can mount externally (Pushpit? Up mast?) ? =>https://www.amazon.co.uk/dp/B072Q54BNX/ref=cm_sw_r_cp_tai_F5NTEbJKQWDKG<=
   3. Or something sim less, like this, that will work abroad. I can't find out much info about it, it seems like a good idea? Or is it just well marketed snake oil? =>https://www.amazon.co.uk/dp/B0834Q5JXG/ref=cm_sw_r_cp_tai_u7NTEbTS6QEA1<=

Final question, I see Navionics now shows the AIS data, making the above worthwhile, however, does it show CPA? Without that, no matter how much I do love Navionics for navigation, it'll always leave me wondering just how close that ship be be passing if Navionics have not figured out the maths yet...

I see nothing wrong with the concept but you can only use one wifi connection to your iPad at a time. So for navigation, the Seatalk to WiFi bridge will give you all the data from the plotter, radar and instruments. You can switch out of the Raymarine app to Navionics but to my mind there’s little point in doing so as you’ve already got all the navigation data with the app. Not sure if the Navionics app can separate out the AIS data from the Raymarine data flow to show you AIS, but you’ve already got that in the Raymarine app.
To access the internet, you’ll have to disconnect from the WiFi Bridge and switch to an internet link. I use my phone to provide a data link for iPads on board, never bothered with anything else for years. I did have a mifi once before phones were good at handling data but not bothered with it for about 6 years or so.

We have a Lowrence plotter and when using it’s WiFi our iPad and Navionics App it picks up gps and ais data from the network, we don’t have a separate WiFi bridge, the Lowrence seems to do this, worth trying your e7. Cannot use both Navionics app and Lowrence plotter view app the same time.

Navionics app does show CPA and alarms now
