azimuth drive

Since azimuth drives seem to be the latest and greatest thing for modern vessels why aren't they being used on sail boats? It seem to me it would make docking and other close quarter manouvering so much easier.

Wouldn't a "sail drive" be considered an azimuthing drive?

First I'll admit that other than seeing them on tugs in drydock, I know nothing. I'm going to guess cost would be the first answer. Second, so far I've only seen them installed as twins, which makes sense to me to really be able to control your vessel. While a single would work, it then seems to me to become a glorified stern thruster, or something similar to having an outboard.

I think azimuth drive refers to the capability of rotating the "sail drive" in any direction to thrust in any direction.

John is correct - an Azimuthing Drive rotate (horizontally, providing steering as well as propulsion.

Fischer Panda, for one, has a Diesel-Electric “Aziprop” for sailboats.
DE-Aziprop

An Azimuth is a horizontal angle, usually measured clockwise from a due North reference plane, where north is 0̊, east is 90̊ azimuth, south is 180̊, and west is 270̊.

Not "just" for sailboats! I'm planning on using one for our trawler.

I would not trust this system too much; yes, it eliminates a hole in the hull,
as well as need in stern thruster (not common on sailboats, IMHO)
BUT: in case of "catching" something underwater you loose propeller plus a real expensive electric motor (might be a set of total ~$7000, if feathering prop),
with poor chances of replacing it fast.

In any case you have to protect these units from all sides VERY well.

Tons of drag - not so good for a sailboat.
