Stretching the definition of TV a little, maybe, but for those of you that are cord cutting and relying on interesting streaming, the YouTube channels Acorn to Arabella (where two guys in the middle of Massachusetts build a 36' wooden boat, starting with cutting down and milling the timber) and Sampson Boat Co. Talley Ho (rebuilding a classic 50' sailing yacht from the turn of the last century) are fascinating. From the tools to the techniques to the sheer ballsy-ness of such undertakings.
I've been watching a lot more of this kind of stuff and way, way less regular TV lately.
