Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an ...
The name changed after another magazine, Marine Propulsion and Auxiliary Machinery, (launched in 1985 by Argus Business Media as a competitor to The Motor Ship) took the title for its own conference. The 2012 event, held in Hamburg , Germany, was the 34th; [ 17 ] the 2013 event will be in Copenhagen , Denmark. [ 18 ]

Experiment was a horse-powered ferry boat.It was a 12-ton, three-masted boat drawing a few feet of water, about 100 feet (30.48 m) long by 20 feet (6.1 m) beam. [3]) in 1807 to 1810, depending on the source.
Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel). AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.
UQM Technologies Expands its Marine Applications with Electric Propulsion System for Mylne Bolt 18 Yacht Tender The Mylne Bolt 18 debuted at the 2012 Monaco Yacht Show This is the second ...
A Z-drive is a type of marine propulsion unit. Specifically, it is an azimuth thruster. The pod can rotate 360 degrees allowing for rapid changes in thrust direction and thus vessel direction. This eliminates the need for a conventional rudder.
A gearbox and clutches enable either of the engines or both of them together to drive the shaft. Two advantages over simply using a single, larger diesel engine of the same total power output are that (1) diesel engines have somewhat better specific fuel consumption at 75% to 85% max output than they do at only 50% output, and (2) there is a weight and size advantage to using two higher-speed ...
