Yes, but it's a shame to pay that amount of money and be left unattended. I hope I can make it work...
If not, I will be forced to sell the Hat for somebody who want to be in OP2 and do a regular active usb gnss and sdr ais instalation. No other solution. Thanks!

After 3 days on, the Hat finally caught satellites and AIS with much better coverage than before in OP2. Suddenly, started working; bizarre, hopefuly it remains that way! Anyway, I already bought a USB GPS/GALILEO/GNSS, and a good quality SDR Antenna.

Well im glad for you. Mine has been up for 30 days without any activity (even the signalk paths are not there) so i dont think its coming back any time soon

Hi!
I reinstalled again and finally used OP3. Ais and gps started working again after a couple of days. However, they stopped working suddenly and after several restarts, and several days, they went back to life one more time. Might this be caused by a lack of power supply? I have a step-down bucket for 3A, maybe is tight with all the usb ports used (sub3. 1 as Ssd, usb 422, hub with several things) I've bought a new step-down bucket with 10 A, let's see if improves, I couldn't install it yet. Thanks!

Am I missing something here? Wouldn't it be easier to just take it off of the raspbi and use it as a standalone device instead of hacking it and losing bluetooth? Or is that somehow much more difficult that I imagine it to be? Bluetooth is essential to my setup, but my system is currently only barely functional with GNSS lock taking forever and other bugginess... what to do?
Thanks a bunch for posting the hack Sailoog! Never again closed source!

I had days of frustration, same kind of yours, just to conclude that I made my same old mistake...
You can see in this thread, how the Moitessier is sensitive to the quality of the power source: https://forum.openmarine.net/showthread.php?tid=1368 It was mainly about AIS reception but I can imagine that will be true for GPS as well. While trying to troubleshoot the "hacked" moitessier configuration on a desk, I used my smartphone charger to power the RPi, the GPS reception was appearing sometimes than disappearing for good, at least I had a confirmation that it should work overall.. Finally I ended up connecting my beuatiful industrial grade power supply that I had to disassemble from the target device and bring to the desk, It works as a charm now. TRACO TMDC 20-2411 I love that power supply for several reasons - low noise and stable, has protection so I am less afraid to burn down my boat, wide range of input DC, so I can use my device both with 12 and 24 V DC, but also take any old laptop charger from scrap and use it for 230VAC operation at home. The GNSS status LED was blinking normal in both situations ( at effective satellite reception and uneffective), so maybe actually the communication itself was adversely affected by bad quality power supply? I am not sure if the green LED blinks normal if it gets fixes..? (please mind that I am a mechanical engineer, know nothing about RF electronics) I wish you good luck with that, after all, lovely piece of abandoned equipment
