The E Series 125 is Hargrave stepping into true superyacht territory, and the first hull carries a name: Resonance. At 125 feet she was a nominee at the 2026 Design and Innovation Awards, recognition that the yard has moved well beyond its cruising-boat roots. Built to RINA pleasure yacht class, she pairs roughly 330 gross tons of volume with the kind of documented engineering a buyer at this level expects.
Power comes from twin Caterpillar C32 engines of 1,900 horsepower, giving a cruising character rather than a sprinting one, with a top speed near 17 knots. Ten guests are accommodated with a crew of seven, a balance that points toward private family use with full service rather than large-scale charter. Displacement runs from 180 tonnes light to 220 tonnes at full load.
The E Series name marks Hargrave’s contemporary design language, and Resonance shows it at a mature scale: clean volumes, long glazing and a three-deck profile that reads as a modern superyacht. As ever, the interior is shaped with the owner, so the next hull in the series need not repeat this one. For a buyer who wants an award-nominated American superyacht with European-style design, RINA classification and a direct relationship with the builder, the 125 is a credible and current option. She is the clearest expression yet of where the yard is heading.

The E Series 125 is tuned for comfortable passage-making rather than outright speed. Twin Caterpillar C32 engines, each of 1,900 horsepower, give a top speed near 17 knots and an easy cruise below it, figures that suit a 220-tonne hull built for range and stability. This is semi-displacement behaviour, where sea-keeping and efficiency matter more than a high top end. The payoff is a quiet, composed ride and sensible fuel burn across a long season. Classification to RINA pleasure yacht standard means the machinery, redundancy and safety systems are documented to an independent brief, which is reassuring at this size and valuable at resale. For an owner who plans to cruise widely and keep the yacht for years, the 125 is engineered around endurance and comfort rather than headline numbers.
The E Series line is Hargrave’s contemporary design language, and at 125 feet it reaches full maturity. Resonance carries a three-deck profile with long horizontal glazing, a clean sheer and balanced proportions that earned her a Design and Innovation Awards nomination in 2026. The styling is restrained and modern, letting volume and line do the talking rather than ornament. Deck spaces are generous, from the foredeck seating to the wide side decks and a layered aft arrangement that steps toward the water. The superstructure is handled so that the upper deck feels integrated rather than added, a detail that separates considered design from bulk. She looks every bit a current superyacht, drawn with a European sensibility and built in Florida.
Ten guests are accommodated across a layout shaped with the owner, the central promise of a Hargrave build carried into superyacht scale. At 125 feet and roughly 330 gross tons the yard has the volume for a full-beam master, generous guest cabins and clear separation between owner and guest territory. RINA classification brings a disciplined approach to the structure behind the finish, while the interior itself is specified to brief, from materials to mood. Natural light is a strength, with the long glazing of the E Series profile carried inside to bright, open spaces. Because the accommodation is bespoke, the second hull in the series can present an entirely different interior. For buyers who treat the layout as the heart of the decision, Resonance shows what the platform can deliver.
Resonance is arranged for a family that entertains. The main saloon and dining area open to an aft deck set up for shaded, open-air meals, while the sky lounge above gives a second, more relaxed social level with panoramic views. The lower aft platform works as a beach club and a base for watersports, and the foredeck offers a quieter retreat forward. A crew of seven runs the yacht from spaces designed to stay out of sight, so service is present without being intrusive. Movement between the decks has been planned to keep guest flow natural and crew flow separate. The result is a superyacht that scales up Hargrave’s social ease rather than trading it for size.
The E Series 125 is built in Fort Lauderdale and classed to RINA pleasure yacht standard, a combination of American construction and independent European classification that gives a buyer documented reassurance. Twin Caterpillar C32 mains, commercial-grade generators and stabilisation suited to open-water cruising underpin the specification, and the delivered Resonance hull means the engineering is proven. As an award-nominated design, she also carries a measure of recognition that supports long-term value. Ownership keeps the Hargrave hallmark of direct access to the yard and an interior shaped to the owner, now applied at superyacht scale. For a buyer who wants a current, classed American superyacht with contemporary design and a short line to the builder, the E Series 125 is among the most compelling choices in the range.
