I do most of my boating alone, hardly watch TV as I don't at home either. I take a lot of instruments (trombone, cornet, guitar, fiddle, concertina) and about three hundred books plus an ereader.
If I lived on again, I probably would get a satellite tv system but for a couple of six week trips a year plus weeks here and there it's not worth it.
What I do miss is the lack of 2nd hand bookshops to replenish my supplies - I used to navigate by them, but most have gone now and charity shops just aren't the same.
