Hybrid or electric? We offer both.
Let us introduce the hybrid version.

What is a hybrid propulsion system?

Oceanvolt focuses 100% on clean electric power and propulsion systems for boats ranging from monohulls and catamarans to non-planing motorboats and commercial ferries. We work directly with boat owners looking to build a new electric or hybrid vessel, as well as those wishing to upgrade an existing boat with an Oceanvolt system. We also collaborate closely with boat builders, supporting them from the earliest design stages whenever a customer is interested in an electric or hybrid.
