Mediterranean Shipping Co (MSC) has snapped up another brace of post-panamax container ships for about $140m en bloc.

The liner operator is acquiring the 6,000-teu sisterships Long Beach Trader and Los Angeles Trader (both built 2007) for a little less than $70m each, according to European brokers.

The vessels will not be delivered until the third and fourth quarter of next year.

But MSC is prepared to pay top dollar as long-term charter rates for traditional panamax and post-panamax vessels remain extraordinarily strong.
