Overview
The 790 Spectre is a fully electric sports boat developed by Frauscher in collaboration with Porsche, combining Frauscher hull and interior design with Porsche electric drive technology to deliver high-precision handling, efficiency and distinctive styling.

Design
The 790 Spectre is conceived around the Porsche electric drive. The lightweight hull and Frauscher design language prioritise clean lines, ergonomic deck layout and clear access routes for onboard operations and passenger movement.

Technical details
A newly developed lightweight hull increases agility, efficiency and range while preserving precise handling. Key technical elements include:

• Automotive-style charging socket for AC and high-speed DC charging
• Central Porsche control unit
• High-voltage battery with battery management system (100 kWh)
• E-machine with power electronics
• Marine Z-Drive propulsion

Highlights
Custom Porsche colour options (including paint-to-sample) and a multi-layer high-precision finish from the Frauscher yard. The combination of Frauscher layout and Porsche e-drive emphasises performance-oriented packaging and refined aesthetics.
