Navig8 Group is expecting big ­returns from its latest investment in the product tanker market, and its principals are not shy about saying so.

Navig8’s London headquarters, chief executive Nicolas Busch and chairman Gary Brocklesby say they think they have found a sweet spot for their near-$600m splash on 16 newbuildings, split equally between LR2 and MR units at China’s New Times Shipbuilding.
