Surface drives?

I think you might be referring to "shaft drives" like you would find on an All Weather Lifeboat, Pilot Boat etc. Uncommon on RIBs- but there are some big Halmatics which have them.

Yeah, displacement or semi-displacement.

Anything like this? If so it's a surface drive - great at high speed - not so good at low speeds.
