About Delphia

Volume production

Groupe Beneteau's 'mindful cruising' marque, born on Poland's Masurian lakes in 1990 — seven displacement motor cruisers of 9.8 to 13.4 m for canals, rivers and sheltered coasts, on Yanmar diesels of 45 to 230 hp or Torqeedo electric drive, designed by Vripack and Tony Castro.

Delphia was born among the Masurian lakes of Poland and has more than thirty years of boatbuilding behind it. Since 2018 it has been part of Groupe Bénéteau, and with that backing set itself a particular ambition: to lead electric boating on inland waters and along the coast, with ranges wholly electric by 2025. What it builds is meant for slow, quiet sailing -- time taken rather than distance covered.
