Mason PEP Team Takes 2nd Place in Unmanned Category of Electric Boat Competition
Congratulations to the Mason PEP team on their 2nd place finish in the “unmanned” category of ASNE’s Promoting Electric Propulsion competition held at the 2021 Multi-Agency Craft Conference (MACC). This represented the culmination of three senior design team’s efforts – a hull team and propulsion team in the 2019-2020 academic year, and a holistic team to pull it all together in the 2020-2021 academic year. Despite pandemic, these students’ hard work paid off the minute their boat entered the water. Proud of y’all. Well done!
