Boxship giant Seaspan Corp has bought two 12,000-teu containerships that are both on long-term charters for about $176m in total.

Including the two latest buys, TradeWinds estimates that Seaspan has spent $1.1bn to purchase 15 ships since September 2019.

The specific vessels that have been acquired were both built in 2018 but were not identified by Seaspan, which is part of New York-listed asset manager Atlas Corp.
