Luff turbulence is less of a problem with a
shunter. Boltrope/track goes on leeward side of the mast and gives a better flow
than for a rotating mast in many cases.

Thanks for the additional information. I must have been mislead by the same articles that confused Chris Ream on that thread you found. Perhaps it was the retrofit that I'd read about.
So it's only the wishbone that rotates, eh?
Well, at least there are no bearings to maintain, and since it's unidirectional, the only downside to a fixed mast is turbulence at the luff.
