New Solar Powered Boat Debuts For Sustainable Marine Travel

Massachusetts-based startup Worden Marine has introduced the TruSolar20, a versatile, zero-emissions boat powered entirely by an array of six 425-watt solar panels. Designed by solar vehicle veteran James Worden, the 20-foot prototype offers a quiet, exhaust-free experience, cruising at five miles per hour on solar energy alone. The vessel can reach speeds of 14 miles per hour using battery power and maintains operation through the night. With a focus on sustainability and commercial viability, Worden is now developing a larger, streamlined model, the TruSolar40, designed for ferry services, river tours, and recreational use.

The TruSolar20, which first hit the water in 2024, features a lightweight hull constructed from carbon fiber and Kevlar. By utilizing commercially available solar panels, Worden aims to keep the technology affordable while ensuring high performance. The larger TruSolar40 model, currently in development, will feature 12 solar panels and an enclosed design. Despite its size, the vessel remains remarkably light, weighing only 9,000 pounds. These boats are highly customizable, allowing operators to configure seating for up to 16 passengers, or add amenities such as bathrooms, bars, or swimming decks to suit specific commercial needs.

Worden, who previously co-founded the solar electric vehicle company Solectria, prioritized designing a vessel from the ground up rather than retrofitting existing boats. To ensure the craft meets regulatory standards, he consulted with a retired U.S. Coast Guard captain early in the design process, ensuring the vessels comply with requirements for commercial operation. While the company has yet to close a sale, Worden is actively engaging with potential customers. He remains committed to the environmental mission of his work, operating his business from a net-positive, geothermally heated facility in North Andover, Massachusetts.
