In 2016 Dutch ocean shipping had approximately 800 companies. The number of merchant and sea towage vessels under the Dutch flag has grown by 43% in the last seven years from approximately 750 ships in 2006 to 1,059 vessels under the Dutch flag in 2016. The total merchant and sea towage fleet under Dutch management on 31 December 2016 comprised a total of 2,012 ships . The average age of the Dutch ships is only 12.5 years. That is about half the life time of an average ship. The Dutch fleet is therefore very modern.
As an outsider and citizen of a postage stamp sized country, which has 19.1 times less inhabitants than the USA, I am therefore surprised about the mini size of the US fleet. The numbers should be the other way around. What went wrong?
