Northman Electric & Hybrid Propulsion Systems

Electric & Hybrid Propulsion Systems

Northman trawlers are engineered to offer multiple propulsion options, allowing owners to choose the system that best matches their cruising style,
efficiency goals, and environmental priorities.
  • Classic Diesel Propulsion
  • Fully Electric Propulsion
  • Hybrid Diesel-Electric Propulsion

Fully Electric Propulsion System

A fully electric marine propulsion system uses battery power instead of diesel or gasoline. Operating range depends on battery capacity and recharge capability. Electric propulsion delivers instant torque, quiet operation, and zero emissions at low speeds, making it ideal for day cruising, short coastal passages and environmentally sensitive areas.
Electric systems are known for their low maintenance requirements, high energy efficiency, and smooth, vibration-free operation.
  • 48 Volts System
  • Air Cooled
  • Silent Operation

Single Electric Drive Configuration

  • Electric Motor: 20KW
  • Battery Bank: 50KWh lithium
  • Battery Range:
  • Up to 5 hours at 4.5 knots
  • Up too 2.5 hours at 5.9 knots
  • Range with Diesel Generator Recharging:
  • Unlimited range at 3.5knots
  • Recharge Time (48V Charger):

Hybrid Diesel-Electric Propulsion System

The Northamn hybrid propulsion system combines a traditional diesel engine with an electric drive, offering flexibilty, redundancy and improved efficiency. The system operates in two primary modes:

Electric Propulsion Mode:

The vessel runs solely on electric power with the diesel engine turned off, providing quiet, emission-free operation.

Charging Mode:

While the diesel engine is running, the electric motor functions as a generator to recharge the battery bank.
A dedicated computer management system continuously monitors performance and automatically regulates RPM during charging to prevent overheating and ensure optimal efficiency.
  • 48 Volts System
  • No need of legacy generator
  • AC can run from battery in silent

Hybrid Single System Configuration

  • Diesel Engine Options: 57HP or 370HP
  • Electric Drive: 20kW
  • Battery Bank: 50kWh lithium
  • Battery Range:
  • Up to 5hours at 4.5 knots
  • Up to 2.5 hours at 5.9 knots
  • Recharge Time (Hybrid Recharge System):
  • Approximately 4 hours

Why Choose Electric or Hybrid Propulsion?

Electric and hybrid propulsion systems provide quieter operaation, reduced emissions, and increased efficiency while preserving the reliability and range expected from a modern trawler. These systems allow owners to enjoy peaceful cruising when desired, with the confidence of extended range and redundancy when traveling longer distances.

Your Questions About Electric & Hybrid Propulsion, Answered

Northman trawlers can be equipped with three propulsion options: traditional diesel propulsion, fully electric propulsion, or hybrid diesel–electric systems. Each option offers different advantages depending on cruising style, range expectations, and operational preferences.
Cruising plans play a key role in determining the right propulsion system. Factors such as typical cruising distance, average speed, access to shore power, time spent at anchor, and desired autonomy directly influence whether a diesel, electric, or hybrid configuration is most suitable.
Fully electric propulsion is well suited for day cruising, short coastal trips, inland waterways, and environmentally sensitive areas. Range depends on battery capacity and recharge capability, making electric systems ideal for owners with predictable routes and access to charging or generator support.
Hybrid systems combine the quiet, efficient operation of electric propulsion with the extended range and redundancy of a diesel engine. This configuration offers flexibility, allowing owners to cruise silently when desired while maintaining the ability to travel long distances without range limitations.
Autonomy requirements—how long the vessel must operate without recharging or refueling—directly impact battery size, generator capacity, and propulsion selection. Longer-range cruising typically benefits from hybrid systems, while shorter, predictable trips may be well suited to fully electric configurations.
Yes. Northman propulsion systems can be configured with different battery capacities, engine options, and recharge solutions to match individual cruising needs. Customization ensures the vessel performs efficiently and reliably within its intended operating profile.
For extended cruising and variable routes, hybrid diesel–electric systems generally offer the best balance of range, efficiency, and redundancy. They allow electric operation at low speeds while preserving the long-range capability expected of a modern trawler.
Yes. Northman electric and hybrid systems are engineered for marine use and managed by computerized control systems that monitor performance and protect components, ensuring reliability and efficiency during operation.
Performance Yacht Sales works closely with buyers to understand cruising goals, typical routes, autonomy requirements, and future plans. Based on this analysis, PYS helps configure the propulsion system that best matches the owner’s intended use, ensuring long-term satisfaction and efficient operation.
Yes. Propulsion selection affects multiple onboard systems, including electrical capacity, weight distribution, and range. Making these decisions early allows for proper configuration and ensures the vessel is optimized for its intended purpose from the start
