My one borked Linux install came from what I’m guessing was a mem leak in Endeavour (Firefox related or otherwise I’ll never know) stopping up an update/upgrade and not finishing all the post install scripts before rebooting. You’ll be fine, but Endeavour is close enough and does look good out of the box :-)
Good place to look is for camper van resources. Many are 12V, and I believe boats tend to be 24/48V, but most guides I’ve found for my van reference boats throughout. Victron and renology both have a ton of their own material.
