I'm new here coming from Bremen, Germany.
My 20 m2 Jollenkreuzer will receive a new wooden mast which I bought already.
A cable for navigation lights is there, but for antenna cables seems to be no space as the mast is wooden with fill pieces.
anyhow, I thought about fitting an GPS antenna and the VHF as well with Wifi similar to the Maiana AIS or the Windsensors.
I know this are important data and the connection should not fail for safety reasons of course.
Happy to hear your thoughts, thanks,

I am using an inexpensive but pretty darn good ublox GPS/compass (it has a basic three axis integrated magnetic compass) board called Suqure M10-25Q. It is just the board with 6 pins but I connected it to an esp32 (the gps is UART and the compass is I2c, so you need to connect to 4 total GPIO ports, plus power and gnd. It works great, I first set up as wifi but since I'm mounting it so close to the RPi I ended up just commenting via USB. The output is NMEA so whether via wifi or USB (i guess in theory you could also use bluetooth with just a couple lines of changed code), signalk connects perfectly. If you want, I'm happy to share the code, but i think the module was like USD15. It's designed for drones and the like so its signal aquisition is great (it's a unblox M10, i think their best GPS), and the antenna is great. Just a suggestion of what worked for me.
