Based on Company estimates, Vision Marine completed approximately 60 on-water demonstration rides across its three featured boats.

"The Lake Berryessa Electric Boat Festival demonstrated why direct market activation matters," said Maxime Poudrier, Chief Operating Officer of Vision Marine. "Electric boating is an experience-driven category. Putting consumers, marina operators, industry participants, media and investors directly on the water gives them the clearest way to understand the performance, simplicity and appeal of the technology. For Vision Marine, approximately 60 demonstration rides across our featured boats represents a meaningful product exposure milestone in a strategic California market."

The event also served as an industry working forum focused on practical requirements for electric boating adoption across consumer and commercial applications. Summit discussions included charging infrastructure, marina electrification, vessel technology, workforce development, commercialization opportunities and policy considerations for the growing electric marine sector.

"Vision Marine's role as Title Sponsor helped bring electric boating directly to the water for consumers and industry leaders," said Ollie Danner, Founder and CEO of Sea Watts. "The event showed that marine electrification has moved beyond discussion, with companies like Vision Marine demonstrating real products in real boating conditions."
