Genco Shipping & Trading has got creative in acquiring three modern ultramaxes in exchange for six of its older handysizes in a non-cash deal believed to involve London fund manager Tufton Oceanic.

Fuel efficiency and reduced carbon emissions have become increasingly major considerations for publicly listed owners.
