I only uses 9,600 TEU capacity vessels for 1 of the Asia - Europe
trade rt, rest bet 4,800 - 8,400
But lots of growth for the Intra - Asia trade, rationalising their
rts now 
But Intra - Asia rts, max size is 4,800 as some ports esp at China,
Taiwan, Thailand, Indonesia cannot handle as well as ports like
Singapore, Hong Kong, Busan, Shanghai, Kaohsuing, Port Klang
(Sadly, it has tidal constraint)
