> From what I understand, a structure needs to be quite massive to get meaningful gravity from a rotating hull unless you attempt to approach ludicrously unsafe angular velocity which would make repair / docking a big challenge

The reason it has to be so massive is that otherwise the difference in the G-forces between your head and your feet can make you sick[1].

They talk about it in the book, it actually makes some of the characters sick

Yeah, I know. I just wanted to elucidate for others who may not have read the book what some important reasons are for making rotating ring structures quire large.
