2026 Custom Franco Gnessi DYD YH NAUTILUS

The Franco Gnessi DYD YH Nautilus is a 223-foot steel megayacht powered by twin electric engines, representing a contemporary approach to large-yacht propulsion. The design, conceived by Franco Gnessi, emphasizes clean lines and deliberate proportion across its 45-foot beam. The yacht achieves a cruising speed of 15 knots with a maximum speed of 17 knots.

Accommodation comprises six cabins served by twelve heads, providing full facilities for extended voyages or entertaining. The layout distributes living spaces across the 223-foot length, allowing separation between owner and guest areas while maintaining the open social volumes essential to a megayacht of this scale.

Built in steel, the Nautilus combines durability with the design freedom that composite hulls cannot match. The electric propulsion system represents a significant departure from conventional fuel-burning engines, positioning this yacht at the forefront of sustainable large-yacht engineering while maintaining the performance and range expected of a boat of this size.
