I have the vyacht NMEA wifi. It seems to be a great unit, unfortunately however, they don't seem interested in supporting the product at all. They were more than happy to answer all my questions until I actually bought one, but have ignored all my requests since they have had my cash in their bank.
I have set the unit up with the NMEA 2000 inputs, and tested it out with the mid wifi APP. It works great. However, once your ipad is connected to the vyacht wifi, you can no longer access the cellular wifi on your ipad.
vYacht claim that it will route my internet too. I have it connected to my Computer by Ethernet cable, and my computer tethered to my iphone for 4g internet, however, despite studying their manual closely, I can't make it work.
Does anyone have any experience of this set up that could offer some help?
