In a landmark move that signals a major shift toward sustainable maritime operations, Arc—a U.S.-based electric boat innovator—has partnered with Curtin Maritime to deliver eight hybrid-electric tugboats in a deal valued at $160 million. This agreement marks the largest commercial deployment of electric workboats in history and sets a new benchmark for clean energy adoption in port logistics.
A New Era for Tugboat Technology
The hybrid tugboats will be powered by Arc’s proprietary electric powertrain, delivering over 4,000 horsepower and supported by 6 MWh battery buffers. These vessels are designed to operate with zero emissions during port maneuvers, drastically reducing the carbon footprint of harbor operations.
This development aligns with the broader energy transition in the maritime industry, which is seeing a surge in alternative propulsion systems, digitalization, and regulatory pressure to decarbonize.

Why Hybrid Tugboats Matter
Tugboats are essential for maneuvering large vessels in and out of ports, but they are traditionally powered by diesel engines that emit significant amounts of CO₂, NOx, and particulate matter. By switching to hybrid-electric propulsion, Arc and Curtin Maritime are addressing:
- Air quality concerns in densely populated port cities
- Compliance with IMO 2020 sulfur cap regulations
- Operational cost savings through reduced fuel consumption and maintenance
This initiative also complements other pioneering efforts like the eWolf electric harbor tug, which underwent sea trials in 2023 and was delivered in early 2024. Learn more about that project here. [Electric H…ritime Hub]
Technical Highlights
Each hybrid tugboat will feature:
- Dual-mode propulsion: Electric-only for low-speed port operations and diesel-electric for extended range
- Advanced battery management systems: Ensuring optimal energy use and safety
- Microgrid charging stations: Designed to recharge vessels efficiently between operations
These vessels are expected to cut fuel use by up to 60% and reduce maintenance costs by 40%, making them environmentally friendly and economically viable.
🌍 Strategic Implications for U.S. Ports
Curtin Maritime, based in Long Beach, California, operates in some of the busiest and most regulated ports in the United States. Deploying hybrid tugs will help meet California Air Resources Board (CARB) emissions targets and support the Port of Long Beach’s Clean Air Action Plan.
This move also positions U.S. ports to compete with global leaders like Singapore, Shanghai, and Rotterdam, which are investing heavily in green shipping corridors and smart-port infrastructure.
🤝 Industry Collaboration and Investment
The $160 million deal is not just a commercial transaction—it’s a strategic partnership aimed at reshaping the future of port operations. It reflects growing investor confidence in green maritime technologies, similar to the $1.55 billion investment announced by Capital Maritime in LNG dual-fuel vessels and CO₂ capture-ready ships.

📈 Market Trends and Future Outlook
The global maritime industry is undergoing a rapid transformation driven by:
- Regulatory frameworks like IMO’s Carbon Intensity Indicator (CII)
- Technological innovation in propulsion, automation, and digitalization
- Investor interest in sustainable shipping solutions
Hybrid tugboats are just the beginning. The future may include fully autonomous electric vessels, AI-powered fleet management, and renewable energy integration through solar and wind-assisted propulsion.
Workforce and Training Implications
As vessels become more technologically advanced, the maritime workforce must adapt. Hybrid systems require new electrical engineering, battery safety, and digital diagnostics skill sets. Training programs and certifications will need to evolve to support this transition.
Norway’s recent push for gender diversity in maritime careers and the Philippines’ role in global seafarer supply exemplify how workforce development is becoming a strategic priority. Explore this topic more in Maritime Hub’s workforce section.
Conclusion: A Blueprint for Sustainable Port Operations
Arc and Curtin Maritime’s hybrid tugboat deal is more than a technological upgrade—it’s a blueprint for sustainable port operations. By combining innovation, environmental responsibility, and strategic investment, this partnership sets a precedent for how maritime companies can thrive in a low-carbon future.
As the maritime industry evolves, stakeholders—including shipbuilders, port authorities, regulators, and investors—must collaborate to scale these solutions globally. The sector has the opportunity to lead the charge in climate action, with hybrid tugboats representing a decisive step in that direction.
