Taiwan's Yang Ming Marine Transport has subchartered a neo-panamax containership for a year in a rare deal that reels in a profit that could reach $47m.

The deal with AP Moller-Maersk opens a potential new trade in the tight containership market: sublets among rival liner operators.

In a regulatory disclosure, Yang Ming said it chartered out a containership at between TWD 3m and TWD 4m ($108,000 to $144,000) per day. That translates to total revenue of between TWD 1.25bn ($44.9m)
