Z Drives, pods, electric hydraulic etc is where the commercial business has been headed for a long time. Dozens of websites for commercial vessels, builders and users of these newer drives can found.

Ever wonder why cruise ships don't normally require old fashioned tugs unless mandated by union agreements? Many of the BC and WA tugs of today have some very neat modern drives, all for good reason.
