Shipping giant Zodiac Maritime is about to take advantage of the red-hot tanker market to offload an 18-year-old ship at a higher price than it bought it for a decade ago.

Some brokers report that a deal for the 150,600-dwt Crescent Moon (built 2004) has already been concluded for $33.5m.

Zodiac declined to comment, in line with standard policy to not discuss commercial transactions.
