This summer, custom builder Trinity Yachts  launched the 190-foot $54.9 million Mi Sueño, featuring a split-level owner’s suite. Wine enthusiasts will appreciate the custom floor-to-ceiling “cellars” made of wenge wood and bronze that flank the entrance from the aft deck.

Patrick Knowles of Patrick Knowles Designs created this feature as a sort of tasting room, where the floor is highlighted by a marble mosaic inlay. Other touches aboard Mi Sueño include a wheelchair-accessible guest stateroom (one of six) and an elevator that connects all decks. —D.B.
