Description

Presentation




Mounted on the transom, the BlueSpin 15 kW Outboard is BlueNav’s most powerful electric propulsion solution, designed for larger vessels requiring high thrust, precision maneuvering and advanced software-assisted navigation.
 Engineered primarily for twin-motor installations, it delivers silent, smooth and intelligent propulsion in hybrid or fully electric configurations.
Despite its power, the BlueSpin 15 kW remains discreet and elegant, retracting seamlessly when not in use while unlocking the full capabilities of BlueNav Smart Navigation.
Fully compatible with NMEA 2000 electrical architectures, the BlueSpin 15 kW is suitable for both new builds and retrofit projects.


Design & Installation


The BlueSpin 15 kW is designed to be installed and operated as a twin-motor system, ensuring optimal thrust, redundancy and 360 maneuverability on heavier displacement vessels.
Mounted directly on the transom, the system requires no structural modification to the hull.
 In hybrid configurations, each unit automatically retracts when the thermal engines are in use and deploys instantly when switching to electric mode, preserving hydrodynamic efficiency and performance.
Its robust construction and balanced geometry make it ideal for premium cruisers, large dayboats and yachts requiring precise low-speed control.


Key Features


  • High-power retractable turbine developed by BlueNav
  • Patented Dynamic Anti-Cavitation Thrust Control for smooth and efficient thrust delivery
  • Designed for twin-motor configuration
  • Transom-mounted solution with minimal visual impact when retracted
  • Reduced maintenance requirements
  • 3D joystick and HMI with intelligent energy management
  • Seamless integration with hybrid propulsion architectures
  • Installation suitable for new builds and refits


  • Smart Navigation Integration


    The BlueSpin 15 kW is fully integrated into the BlueNav Smart Navigation ecosystem, transforming high-power electric propulsion into a complete assisted navigation and positioning system.


  • Positioning functions
  • Virtual Anchor
  • Dynamic Positioning System (DPS)
  • Drift Lock
  • Maneuvering assistance
  • Docking 360
  • Lateral Docking
  • Autopilot functions
  • Heading Hold
  • Course Hold
  • Waypoint Tracking
  • Speed Control


  • These software- driven features provide exceptional control, safety and comfort, even on large vessels and in demanding harbor environments.


    Operational Advantages


    Designed for twin installation, the BlueSpin 15 kW delivers exceptional thrust and full 360 maneuverability, enabling silent harbor operations, precise docking and stress-free handling of large boats.


    twin BlueSpin 15 kW configuration is capable of equipping vessels up to 18 tons, with a combined thrust of 420 kg*, ensuring confident control even in wind or current.


    The system is optimized for use with a recommended battery capacity between 20 and 45 kWh, depending on vessel size, operating profile and desired electric range.


    In hybrid applications, the BlueSpin 15 kW complements internal combustion engines by providing silent electric propulsion, reduced emissions and unmatched low-speed precision.
