Go for signalk, no question! Runs on linux or windows but a raspberry pi is perfect for use on a boat, openplotter has everything you might need.
It's all in there, node-red available as a signalk app and mqtt available as an app and as a node-red node. Little signalk can't do.
Sorry, deleted the flows already but looked ike this >
TCP node reads the data signalk puts out on TCP 10110, which can be basically anything coming in which can be an nmea sentence. This get sent to a cloud mqtt broker. Other end is pretty much the reverse though would be better going mqtt to UDP the set up a signalk connection to the udp port. Then you gain all the benefits of having the data as signalk.
