The Commercial Harbor Craft Conversion Kit is a fully electric retrofit package designed to replace conventional marine engines with zero-emission propulsion. Developed by Vita Power US, Inc., the system supports vessels operating in ports, harbors, and coastal waters, giving operators a practical path to clean, modern propulsion without replacing their entire fleet.

The kit is designed for engines in the 120–134 horsepower range (≈ 89–100 kW) and can be configured with 19–500 kWh lithium-ion batteries, allowing operators to tailor performance to duty cycles and operational needs. With this flexibility, a wide range of harbor crafts can be electrified.

Every aspect of the conversion is engineered for durability and ease of integration. By leveraging proven marine battery technology and high-torque electric drive systems, operators gain reliable thrust, quieter operations, and lower running costs. The system eliminates exhaust, fuel handling, and oil changes, reducing both downtime and long-term maintenance.

Charging is simple and scalable, with compatibility for advanced DC shore power and zero-emission bunkering systems. Infrastructure incentives are available to support the installation of charging stations, ensuring efficient turnaround times and high uptime for converted vessels.

With CORE funding available to offset costs, the Commercial Harbor Craft Conversion Kit offers a practical way for fleet operators to modernize, comply with upcoming emissions requirements, and reduce their environmental impact while keeping proven hulls in service.
