Benetti Dagger: Inside the 67m Hybrid Superyacht

Benetti Dagger is a 67-metre B.Now superyacht built around a modular hybrid propulsion system, with quieter low-speed operation and greater flexibility designed into everyday life on board.

Benetti Dagger and its hybrid propulsion system

Built at Benetti’s Livorno yard, Benetti Dagger (FB288) combines a steel hull, aluminium superstructure and 1,334 GT of interior volume. RWD designed the exterior, while Sinot Yacht Architecture & Design created the custom interiors. The yacht was delivered in 2026.

The hybrid system combines two main engines, three generators, shaft generators and a 360 kWh sodium-metal-chloride battery pack. Its significance is less about the battery figure than what happens when the yacht is moving slowly.

Benetti Dagger has three operating profiles. Enhanced Comfort Mode uses electric propulsion at 7 knots, with the main engines switched off; Benetti positions it for coastal cruising and night passages. Extended Range Mode runs at 12 knots using the main engines, with shaft generators supplying the yacht's hotel load. Benetti states that this configuration can reduce fuel consumption by up to 15% compared with a conventional diesel-mechanical installation. Eco Transfer Mode, at 10 knots, combines one main engine with battery support for longer passages.

What hybrid technology changes on board

For guests, the practical difference is acoustic rather than numerical. At low speed, the electric mode reduces the need to run the main engines, while battery peak-shaving helps manage changes in electrical demand. At anchor, Benetti says the batteries can support hotel services with the generators shut down for around two hours.

That approach places propulsion closer to interior design: reducing noise and vibration becomes part of how cabins, lounges and outdoor spaces are used. On Benetti Dagger, hybrid technology is therefore less a standalone engineering feature than another component of the onboard environment.
