The Sirena 68 is an ocean-going motor yacht designed for efficiency, comfort, and performance. Featuring naval architecture and exterior styling by Frers Naval Architecture & Engineering and interior decor by Cor D. Rover Design Studio, the vessel incorporates a hybrid carbon fiber superstructure that significantly lowers the center of gravity while increasing stability and structural rigidity. Interior layouts feature flexible accommodation options including a full-beam master suite with his-and-hers heads, bow VIP cabin, twin guest cabin, and optional aft crew quarters, alongside curated decor palettes (Serenity, Inspiration, and Elegance).
