Jakob:
Today the temperature was tolerable (above 0) and the light good so I spent a couple of hours mapping the NMEA 2000 / Seatalk ng network on board. I haven't had time to devote to such details before.
There are many interesting sensors etc. that can be installed to get an overview of all possible parameters. We'll see what happens... The engine may need to be monitored, e.g. And the lake water temperature, it might be interesting to log.
I also measured the knitting bunk, which will be better adapted to be storage for sails etc. There will be no cushion there next summer.
