There are so many skills that could potentially aid a new liveaboard in maintaining their boat. I'm thinking - electrical knowledge, woodworking, welding, engine-wrangling, etc.
As somebody with a low starting base in all things mechanical, I don't have the capacity to learn all that is required in-depth, but I would really like to throw myself into learning one or two of these areas in order to reduce my reliance on paid help and favours.
So if you were just starting out (for context - I am pre-boat and just planning ahead), and didn't know what you know now - what would you prioritise?
Beyond boat-handling skills, what topics would you prioritise to give the best chance of avoiding issues and making repairs and modifications while out on the cut?
