Yeah i agree with what you say guys.

When one looks closer almost all ship designs originating somewhere in EU ship yards. At least I never saw a todays ship deriving from Chinese Dhow(or Arabian or whatever else) Most none european yards got sooner some plans from EU yards and later changed small things and declared it their design.

This is one of many very similar Voith Tractor tugs built over the years. It is true that the first one were built by McTay. However the very first design originate from Voith in Germany. The last models from South Africa have very diferent funnels.

You do know the chinese have a habit of copy other designs, and maybe this has happened here, now to mention it i wouldn't be surprised if mctay marine actually sold them the design. or the license to build it,

Ok if so then tell me how they came up with a design very very similar to this tug, which was designed in the late 80's by mctays design team, here is a mctay tug of the same Dimensions. > http://www.shipspotting.com/gallery/photo.php?lid=2006370

"The tugs have been designed locally to a Southern African Shipyard design by the Durban firm of Peter Volschenk Naval Architect, which was also instrumental in the design of five earlier tugs for the National Ports Authority, hull numbers T301 – T305." http://ports.co.za/news/article_2007_09_11_4111.html
