The story

The new member of our family, SIALIA 57 is a big step towards sustainable yachting. A custom chase available in fully electric, diesel-electic or diesel versions. Propulsion system, developed by AMPROS, is unique on the market. Decades-long experience in automotive industry is translated into a powerful, efficient system that can deliver an unparalleled power in a compact package.

Full carbon chase offers ample deck space with multiple lounge area's and an interior space with up to two separate cabins and a spacious day-head. Layout can be customized to cater for your requirements and wishes.

Propulsion system is modular and can be customized to meet the clients’s requirements. Battery capacity can be upgraded up to 1080 kWh with a range extender power up to 390kW. Net AC charging and power DC charging are possible. Running the diesel-based range-extender for less than an hour will fully charge the batteries of 256kWh.

Working with this system we can “electrify” all our tenders, offering the same quality of hardware and software. The system is more redundant than regular diesel based systems plus we offer a world-wide service support.
