Sustainable materials, such as steel, wood, leather and composite teak decking, give a nod to the owner’s determination to employ a lighter carbon footprint, though the biggest sustainability breakthrough lies with the boat’s propulsion and slow boating efficiency. Though equipped to run a 75kW diesel generator, the Steeler 61S Electric is also equipped with a 90kW electric propulsion motor and can run on shore power.
“The owner was determined to have the most sustainable boat possible, and one that can adapt as battery technology develops,” says Hans Webbing, owner of Steeler Yachts. “To date, the owner regularly enjoys eight hours of continuous sailing at 5 knots on batteries alone, with normal energy consumption onboard and without needing to engage the diesel genset.”
When cruising at 6 knots, the boat averages a 2000 nautical mile range. Solar panels and windmills mounted on the roof help to feed the 184kWh battery pack.
