A look back at the Round the Island electric-boat set in 2023 by SpiritBARTech35EF, a 35-foot all-electric foiler that circumnavigated the Isle of Wight in 1 hour 56 minutes. Styled like a 1930s rum runner, the boat has a range of around 100nm and five hours of motoring on a single charge, according to developer BAR Technologies.
