	Cruise Ship Project
		The first large passenger vessel with COGAG system was, the car-ferry FINNJET of May 1977 which can link the 660 nautical miles between Finland and Germany in 22h30min at the average speed of 30.5 kts.
		By the way, she's no longer a COGAG ship since the 1981's refit because, due to economical recession in Europe, two 15,500 HP Wartsila Diesel engines were added (areas on the main car deck were sacrificed) to reach 18-20 kts and do the same trip in 38 hours during off-peak saison.
		This is in fact a sort of COGAG system which is improved and not a COSAG one.

	Patent 4369630: Combination drive system for ships
		The advantage of using two turbines is that a small turbine operating at maximum capability is more fuel efficient than a large unit operating at low power output.
		In order to achieve the coupling of both engines to the shaft in a CODAG or COGAG system, it is necessary to provide a complex gearing and clutch arrangement.
		More particularly, a major shortcoming of the combined systems is that since the main driving and gas turbine engines operate in a different manner, at different speeds, sophisticated, synchronized linkage arrangements are required to simultaneously couple both engine outputs to the drive shaft.
