Seagoing Hybrid Systems


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

System Functions

  • Whisper quiet electric operation yet the vessels standard diesel engine remains available to meet high end power requirements.
  • Whilst sailing the system regenerates a significant and useful amount of electricity from the freewheeling propeller.
  • 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

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