Don’t be fooled by the fact that Callisto is “only” 139’4” (42.5 meters). She is every bit as custom as her much larger predecessor with the same name. Since the owners were—and remain—happy with the bigger build from Feadship, they returned to the shipyard for this second time around.
In fact, the owners took delivery of the 205-foot (62.5-meter) Callisto in 2006 and still use her around the world. Additionally, they’ve taken her to Feadship for refits twice in that time. For their newest megayacht, they knew exactly what length they wanted, since they had a specific berth in mind. They knew, too, that they wanted a cruiser capable of at least 20 knots and some equally capable alfresco entertaining areas.
The speed ultimately came down to a series of design refinements from De Voogt Naval Architects and the owners’ team. All-aluminum, versus steel and aluminum, construction naturally made sense, as did a powerful MTU package. Multiple designs, computer analyses, and model tests later, Callisto has a subtly different design directly beneath her nearly plumb bow. It should lower resistance at high speeds, allowing an anticipated 21-knot top end, plus reduce pitching. At 11 knots, meanwhile, the megayacht still should see a good range of 3,000 nautical miles.

The alfresco spaces received just as much attention from the same design studio and the owners’ team. For instance, Callisto has a swim platform suitable for tender boarding, but also for dining. Unusually, the forward bridge-deck area accommodates sun lounges, a big seating area, and a table. The oversize sundeck, meanwhile, has wind-breaking glass walls forward and to each side. However, the forward glass wall can lower for air flow. The deck further has more seating and sunpads fully forward, plus lots of shade overall.
Callisto’s owners want time spent inside to feel as fresh and sunny as days outside. Therefore, Sinot Yacht Architecture & Design prioritizes light tones throughout the lounges and staterooms. This includes the full-beam (30 feet/9.2 meters) bridge-deck lounge and the four guest staterooms below decks. Two of those staterooms are full beam as well. The owners, of course, reserve the forward main deck for themselves.
The owners want heads to turn whether Callisto is cruising leisurely or swiftly. Angular lines, especially one just forward of her nameboard running toward the bow, lend sporty appeal. Simultaneously, these lines help meet the owners’ request for a relatively low, compact stance.
While the owners didn’t get to visit the shipyard as much as they would have liked due to the pandemic, they are weeks away from having their second Callisto all to themselves.
