2. get another wifi dongle and have AP enabled AND wifi connection to inet. (I configured AP to wlan0 and wifi-dongle wlan1 - have seen that others have it opposite but cannot see any difference) 

Another wifi dongle can be really handy onboard, openplotter can act as a wifi repeater so you can get a good usb wifi dongle/antenna and use this to pick up weak networks and rebroadcast  round the boat, or if using a mobile phone for web access it's handy to get at node-red & nmea data without having to log onto the openplotter network, just log onto the mobile network with openplotter  get the IP address from the wifi OP tab.
