Helios Marine

Electric only

Helios Marine is a Bulgarian builder of electric boats based in Burgas, registered as Хелиос Марин АД and founded by brothers Dragomir and Dimitar Enchev. The company works to a vertically integrated model, developing its own LFP battery systems, electronics and vessel-control software alongside the boats themselves, and it sells those systems as propulsion packages to other builders and for retrofits as well as fitting them to its own hulls. It listed on the Bulgarian Stock Exchange in 2026 and opened a production and R&D facility in Burgas the same year. Its range is the Sigma 4.5 watercraft, the Omega 7.2 day boat and the Alpha 14.5 catamaran, of which only the Omega 7.2 is in serial production; the Omega 7.2 won the Gustave Trouvé Award in the under-eight-metre class.
