With a Terence Disdale interior and fully equipped gym, she has six staterooms for 12 guests in a full-beam master suite, three doubles and two twins. An elevator serves the lower, main and bridge decks. Guests are served by 16 crew, while a Michelin-star trained chef heads up the galley.

“She is a fantastic charter yacht with the highest spec imaginable. She is immaculate throughout, and the owners have appointed a world-class professional crew to look after charter guests. The toy list is impressive too, with two Hinckley tenders, and a whole host of other tenders and water toys,” says Cristabel Nye, charter broker at Camper & Nicholsons International, through whom the yacht charters.

Callisto’s big sundeck houses a large hot-tub and a sunbathing terrace forward, while dining areas, casual sofas and armchairs create an ideal outside space for entertaining family and friends.

The steel-and-aluminium yacht, with a cruising speed of 12 knots, is available for a special rate of $368,000pw instead of her usual rate of $460,000pw high season, and $332,000pw instead of $415,000pw low season. Callisto’s Caribbean winter will be spent in the central Caribbean seas.
