Euroseas has picked up two secondhand intermediate container ships from Seaspan Corp, further growing the active fleet to 18 vessels in a booming boxship market.

The Aristides Pittas-led owner has bought the 4,250-teu Seaspan Melbourne (built 2005) and 4,250-teu Seaspan Manila (built 2007) for $37m.

Both ships, which Euroseas has acquired initially with its own money, come with longterm charter deals.
