Arc,
I view “semi’ as meaning partially.
So a boat partially planing like a GB32 running 11 knots is riding up on it’s bow wave to some degree. Not out on top but partially planing. Semi-planing.

But if I’m not wrong we (on TF) don’t use that expression. But I don’t see every word. The thread is directed at FD and SD or the gap there-in. But of course there is a “no mans land” between semi-displacement and planing too. But there I see the gap much more clear and far less no man’s land.
