Massachusetts startup Worden Marine has developed two solar-powered boat designs, the 20-foot TruSolar20 and the larger TruSolar40, for potential ferry, tour and recreational uses. Founder James Worden says the company is discussing the boats with possible customers, but it has not closed a sale.
Massachusetts startup Worden Marine has developed two solar-powered boat designs aimed at ferry routes, river tours and other small commercial or recreational uses. Founder James Worden says the company is talking with possible customers, but it has not yet closed a sale, leaving the boats’ commercial prospects unproven.
The company’s prototype, the 20-foot TruSolar20, carries six 425-watt solar panels in a canopy above the boat. During a late-August trip on the Charles River described by Canary Media, the boat cruised at about five miles per hour on a mostly cloudy day using power from its panels. Worden said it can reach eight miles per hour using solar power alone in sunnier conditions, and nearly 14 miles per hour when drawing on its battery.
The prototype, named Anita after Worden’s late wife and business partner, first went on the water in 2024. Worden Marine is also developing the TruSolar40, a larger, enclosed design with 12 solar panels. The company says buyers will be able to configure seating and other features for their intended use. The larger model could be arranged to carry up to 16 passengers, according to the report.
Worden said the boats are designed from the ground up for electric propulsion. The hull uses carbon fiber and Kevlar, materials selected to make it lightweight and strong. The company plans to use commercially available solar panels, which Worden said cost about 20 cents per watt of capacity. The TruSolar40 is expected to weigh about 9,000 pounds when fully fitted out, he said.
The Commercial Test for Solar Boating
The designs could give ferry operators and tour companies another option for reducing emissions from short trips on the water. During the reported Charles River demonstration, the TruSolar20 ran without exhaust, and the reporter heard only the breeze and onboard music. That describes one trip, not a measured emissions comparison or a guarantee of performance across routes and weather.
The central question is whether customers will buy and operate the vessels. Worden told Canary Media that Worden Marine has not closed any sales, though it is speaking with potential buyers. Without orders and operating experience, the company’s ability to bring the designs into regular service remains uncertain.
Worden’s Solar Vehicle Background
Worden has worked on solar-powered vehicles since the 1980s, when he built a solar go-kart for a Massachusetts state science fair. At the Massachusetts Institute of Technology, he helped start the school’s Solar Electric Vehicle Team. He later co-founded Solectria with Anita and helped establish Solectria Renewables, a photovoltaic inverter company acquired in 2014. He stayed on as co-CEO until 2017.
Worden told Canary Media he began planning a solar boat about four years before the report. The TruSolar20 is not the first solar-powered commercial vessel: the report says a Coast Guard-approved solar boat began carrying passengers on the Hudson River in 2018. Worden Marine worked with a retired Coast Guard captain during development to understand commercial certification standards and began working with the Coast Guard before final designs were drafted.
Sales, Certification and Real-World Use
No customer sales had been completed at the time of the report, and Worden Marine did not identify prospective buyers or provide a timetable for orders. The company’s discussions with possible customers do not establish that any vessel will enter service.
The report describes the company’s work with the Coast Guard on applicable commercial standards, but does not say whether either design has received final certification. It also does not provide the boats’ purchase prices, operating costs, battery capacity, range under varied conditions or measured emissions reductions. Performance will depend on factors such as sunlight, speed and battery use; the report gives example speeds but not a full independent performance assessment.
From Prototype to Passenger Service
The next practical milestones are further design work, any required certification, and a customer willing to buy or operate a boat. Worden Marine is developing the TruSolar40 and says its layout can be tailored to different missions. Options described by Worden include radar, a small bathroom or bar, and a rear deck that could support swimming.
Worden Marine has not announced a delivery schedule or named a launch customer. Until it does, the TruSolar20 remains a working prototype and the larger TruSolar40 a developing design. Prospective operators and passengers will need more information about certification, cost, service conditions and performance before the boats’ commercial role is clear.
Key Questions
What is Worden Marine developing?
The Massachusetts startup is developing the TruSolar20, a 20-foot solar-powered boat, and the larger TruSolar40 for ferry, tour, recreational and other small commercial uses.
How fast can the TruSolar20 travel?
Canary Media reported that it cruised at about five miles per hour on solar power during a mostly cloudy Charles River trip. Worden said it can reach eight miles per hour on solar power alone in sunnier weather and nearly 14 miles per hour using battery power as well.
Has Worden Marine sold a boat?
Not at the time of the report. Worden said the company was in discussions with possible customers but had not closed any sales.
Is the TruSolar40 certified for commercial passenger service?
The report says Worden Marine worked with the Coast Guard during development to understand commercial standards. It does not report final certification for the TruSolar40 or the TruSolar20.
How many passengers could the larger boat carry?
Worden said seating on the TruSolar40 could be configured for up to 16 passengers. The report does not give a confirmed operating schedule or identify a ferry or tour operator.
