Callisto offers everything that one could desire in a 65.00-meter yacht without compromising the sleek yet classic exterior lines. A long profile, vast overhanging clipper bow and large architectural windows make her a modern-day classic. The funnel sweeps up the deck, offering a nice moving element to the whole. Callisto is packed with high-tech features such as the hidden tender garages in the forward quarter of the bow and secret door in the curvaceous transom, which opens to form a vast bathing platform to receive guests arriving by tender. In 2024 she returned as Nectar to Feadship for a refit.
