I'd like to know if they ever nearly died (or became very uncomfortable) from running out of food, broken boat, or otherwise.
Their boat is very small and has only one engine, and it looks like they will sail thousands of kms in one leg on occasion.
I am soft. If I must do this, and I would kick and scream, I would sell my house and buy a yacht with megalitres capacity of water, batteries, refrigerators, and starlink. But I do not think that I could be happy doing this. I would find it more anxious than normal life.
Somewhat unintuitively, smaller vessels have a strength advantage, assuming a well-made closed-top vessel... your main risk AIUI is getting dismasted in a capsize.
TL;DR is strength increases with square of the length, forces acting on the vessel increase with the cube of the length.
This guy is the champion of tiny blue-water vessels:
