Hybrid propulsion system
The term ‘hybrid propulsion system’ refers to a boat that has two independent drive systems for the propulsion. In most cases these are a diesel engine and an electric motor.

Hybrid power system
The main characteristic of a hybrid power system is that it uses more than one energy source to generate power, e.g. diesel fuel, electric shore power, wind power, solar power, hydrogen or power generated by the yacht’s propeller while sailing. The electric power can be stored in batteries or a supercapacitor.
