Retrofit of Hybrid Propulsion Systems
Unlock Efficiency with a Hybrid Retrofit
Hybrid propulsion pairs a traditional diesel engine with high-torque electric motors and smart energy management. The result: meaningful fuel savings, quieter operation, and a smaller environmental footprint—without sacrificing range or reliability.
At yachtservice.me, we deliver turnkey hybrid retrofits: engineering, component sourcing, installation, software calibration, sea trials, and ongoing care.

Key Benefits
Vessel evaluation & energy analysis
Full audit of propulsion, hotel loads, HVAC, thrusters, and planned duty cycles to size motors, inverters, and storage correctly.
Component selection & sourcing
Marine-certified electric motors, bidirectional inverters, DCDC chargers, shaft or gearbox integration kits, and battery systems (Li-ion by default; fuel-cell options on request).
Installation & systems integration
Clean mechanical integration with existing driveline, secure battery mounting with ventilation and fire protection, and tie-ins to nav, throttle, and monitoring.
Software configuration & calibration
Energy Management System setup, charge/discharge logic, load-sharing maps, and mode profiles (harbor, docking, anchor, cruise).
Sea trials & performance testing
Verification of electric-only range, hybrid assist curves, regeneration (if applicable), fuel consumption baselines, and emissions reduction targets.
Problems We Solve
How long does a retrofit take?
Typical projects run several weeks, depending on yard access, battery sizing, and integration complexity.
Do I need to change my gearbox or shaft?
Often no. Many yachts accept inline or parallel-hybrid kits; we confirm during the survey.
What electric-only range can I expect?
It depends on displacement and battery size. We model range for your cruising speed targets during the design phase.
Can I recharge while underway?
Yes. The diesel can charge the pack via the EMS; some setups also support shaft regeneration under sail or at certain RPMs.
How is safety handled?
Marine-rated Li-ion systems include BMS, thermal monitoring, ventilation, and dedicated fire protection zones per class guidance.

- Enhanced fuel efficiency
- Cruise on electric at low speeds and optimize diesel load for best specific fuel consumption. Intelligent EMS reduces unnecessary generator hours.
- Lower emissions
- Hybrid modes cut CO₂, NOx, and particulates to support modern environmental standards and sensitive marine areas.
- Quieter, smoother cruising
- Electric drive removes low-speed vibration and dramatically reduces noise for a more luxurious onboard experience.
- Versatility by design
- Seamlessly switch between diesel, electric, and hybrid modes. Prioritize silence in marinas, efficiency on passages, and power when you need it.

Problems We Solve
- High fuel spend at low speed → Electric low-speed modes and optimized diesel loading.
- Noise & vibration complaints → Silent harbor entries and smooth maneuvering.
- Generator dependency at anchor → Hybrid storage covers hotel loads with fewer gen hours.
- Environmental access limits → Cleaner operation for protected areas and modern compliance expectations.
- Custom engineering for your hull form, displacement, and mission profile.
- Trusted components from leading marine technology providers.
- Deep integration with helm controls, alarms, and remote monitoring.
- Measured outcomes via sea-trial data: fuel, range, noise, and emissions deltas.
- Lifecycle support with preventive maintenance and battery health oversight.

Yacht ownership brings unparalleled freedom and luxury, but it also comes with a carbon footprint due to fuel consumption, energy use, and maintenance activities. Carbon offset solutions help yacht owners neutralize their environmental impact by investing in projects that reduce greenhouse gas emissions globally. From renewable energy initiatives to reforestation programs, these solutions contribute to a healthier planet while maintaining your yacht’s exceptional performance.
Access to fresh, clean water is essential for yacht owners, especially during long voyages. Watermaker systems convert seawater into potable water using advanced reverse osmosis (RO) technology, ensuring a reliable and sustainable water supply. Proper installation, calibration, and maintenance of these systems guarantee consistent performance and extended equipment lifespan.
