Regeneration vs. Sailing: A Symbiotic Relationship

I n sailing jachty equipped electric disquirs, regenerative braking is especially valuable. When thee wind fulls thee gails, thee vessel moves forward andthee water flowing paste thee hull turns thee propeller. Thes allows thee vessel of letting that motion go to waste, thee electric motor acts as a generator, topping up thee batteries shore. This allows thee vessel to maintain elecational systems - lights, vigation - with runt ning a generr using shors.
