"Baba's"; Hargrave's 56-meter Flagship The 56-meter flagship of the Hargrave Custom Yachts is called "Baba’s". She was built to a design by Unique Yachts with an interior and Naval Architecture by HSY Yachts. This isn’t necessarily new territory for Hargrave as they have built this large before taking it all the way back to 1991 with the 184-foot "Katamarino" currently known as "Paris" at Amels. Jack Hargrave designed the exterior on that superyacht but it was built at Amels. She (Baba's) features a steel hull and aluminium superstructure construction.
