The E-Series Tri-Deck yachts were developed by Hargrave Superyachts, building on the same Jack Sarin–engineered hull forms that underpin the E-Series platform. Designed from the outset around volume, livability, and long-range use, the Tri-Deck configuration reflects Hargrave’s focus on practical layouts, structural consistency, and repeatable engineering. The platform is characterized by generous interior volume, minimum 7.1-foot (2.15 m) ceiling heights, and layouts developed to support extended time aboard.

The E-Series Tri-Deck follows the same Owner-Driven mentality that defines Hargrave’s approach to yacht building, combining a proven foundation with the flexibility to develop each yacht as an individual project.
