Cleopatra C (ex-My Gail III) was launched in 1985 as the well known MY GAIL III. This was the first project where DIANA teamed up with the legendary designer Jon Bannenberg. DIANA was responsible for the hull lines, and construction of hull and superstructure, where Bannenberg mastered the styling of the superstructure and interior.

With her 57.00m of luxury, innovative design, and worldwide cruising capabilities it still is one of the finest motor yachts sailing the oceans.
