Around the time Posidonia took place in 2018, Greek container ship company Danaos looked on the verge of collapsing.

Fast-forward four years and the John Coustas-led owner of more than 70 boxships could not look in better shape.

It reported $1.05bn in annual net income for 2021, perhaps the highest profit ever recorded by a listed Greek shipping company.

Danaos is not the only Greek container shipowner to have been riding high on supply disruptions caused by the pandemic.
