Hailed as the ‘Tug of the Future’, the ground-breaking electric-powered ElectRA Series of harbour tugs is the first of a new generation of emissions-free tugboats from Sanmar Shipyards that will have a major impact on cutting emissions in any busy harbour they work in. ElectRA tugs, available in a range of sizes (19-28m) and power outputs (40-85 TBP), are the result of Sanmar’s ongoing collaboration with Robert Allan Ltd and Corvus Energy to build low and no-emission tugs utilising alternative fuels and innovative technological advances to protect the environment and build a sustainable tug and towing industry.
