Global Ship Lease has prolonged a fixture for one of its post-panamax boxships by another three years.

The London-based company has agreed to continue chartering the 9,115-teu UASC Al Khor (built 2015) through a new contract starting in June and ending in the second quarter of 2022.

The deal is expected to make about $28m for the Ian Webber-led company, which did not indicate the length of the current charter.
