Cargo vessels are set for a design change embracing sleeker hulls and hybrid propulsion systems, according to London-based Rolls, which is helping to develop a ship featuring a 180-foot sail augmented by bio-methane engines and carrying 4,500 tons.

“We’re at the dawn of a transition,” said Oskar Levander, vice president for innovation at Rolls’s marine unit, who predicts a switch to alternative fuels such as dimethyl ether and liquid natural gas, as well as “high-tech wind.”
