Koopmans 40

Print this boat
A legend... is that an exaggeration? No, not in the case of this boat. Her name: Bylgia. She was built according to the wishes of Eilco Kasemier. This well-traveled Grand Dame has been fully restored since 2020, with love for her history and an eye for detail. The interior feels warm, spacious, and pleasant. The navigation table is generously sized. All materials to restore the boat to its original condition (including the dome window and rigging) are present. With this boat, you are buying a piece of Dutch sailing history. The lady is ready for her next adventure. Are you the one to join her?
