Seagoing Hybrid Systems


No two hybrid requirements are the same. Our hybrids have applications in seagoing sailboats (monohull and catamaran), small inspection launches and water taxis. We work closely with builders to design hybrid systems for their particular applications.

System Functions

  • Whisper quiet electric operation, yet the vessel's standard diesel engine remains available to meet high-end power requirements.
  • While sailing, the system regenerates a significant and useful amount of electricity from the freewheeling propeller.
  • The system can be operated as a stand-alone diesel generator when at anchor or if shore power is unavailable – this can support air conditioning.


System Features

  • A highly efficient system with much-improved fuel consumption figures. Extended cruising range on limited fuel resources.
  • Built-in redundancy: if the diesel engine fails, you can use the electric drive and vice versa.
  • The off-the-shelf system is suited to both new-build applications.
  • Simple, user-friendly controls.
  • It is an intelligent power management system and can be combined with other renewable energy sources.
  • A cost-effective solution that can be customised around your vessel's power requirements.
