Massachusetts startup Worden Marine has developed the solar-powered TruSolar20 and a larger TruSolar40 for potential ferry, tour and recreational use. Founder James Worden says the company is talking with prospective customers, but has not made a sale. Commercial certification, customer demand and the boats’ operating performance across different conditions remain key questions.
Massachusetts startup Worden Marine is developing customizable, solar-powered boats for ferry routes, tours and other small commercial uses, with founder James Worden saying the company is in discussions with potential customers but has not yet made a sale. Its first design, the 20-foot TruSolar20, runs on solar panels and battery storage, while a larger model, the TruSolar40, is in development.
Canary Media reported that the TruSolar20 prototype, named Anita, first went on the water in 2024. During a Charles River demonstration in August 2026, six 425-watt panels on its canopy supplied enough power to cruise at about 5 miles per hour on a mostly cloudy day. Worden said that in sunnier conditions it can travel at up to 8 miles per hour on solar power alone, and approach 14 miles per hour using stored battery power. Those figures describe the reported boat and conditions; they are not independently established performance guarantees.
The company’s second design, the TruSolar40, is twice the length of the smaller boat and half again as wide, with 12 solar panels and an enclosed cabin. Worden told Canary Media that it will be configurable for different uses. Seating could accommodate up to 16 passengers, and possible additions include radar, a small bathroom, a bar or a rear deck. The company says the fully fitted boat is expected to weigh about 9,000 pounds.
Worden Marine aims to build its boats specifically around electric propulsion and solar power. The report says the hull uses carbon fiber and Kevlar to keep it light and strong, while the company uses commercially available panels to help control costs. Worden said the startup has not closed any sales and is speaking with several possible customers. No prices, delivery schedule or signed orders were reported.
A Test of Demand for Solar Boats
The designs address a niche in passenger transport where operators may value quiet operation and no exhaust from the boat, including river tours and short ferry routes. A solar canopy paired with batteries could reduce the need to refuel during service, depending on route length, speed, sunlight and charging access. The reported demonstration shows how the TruSolar20 performed on one outing; it does not establish how the boats would fare across a full commercial schedule or in varied weather.
For Worden Marine, the near-term test is commercial. Potential uses and configurable features may help the startup appeal to different operators, but it has yet to report a sale. If customers do not emerge, the designs may not reach the water in regular service. The company has not disclosed its pricing or the economics customers could expect, so the cost case remains unclear.
Worden’s Solar Vehicle Background
Worden’s work on solar vehicles dates to the 1980s. He and his wife, Anita, helped start MIT’s Solar Electric Vehicle Team and later founded Solectria, a solar electric vehicle company, and Solectria Renewables, which focused on photovoltaic inverters. The latter company was acquired in 2014; Worden remained co-CEO until 2017, according to Canary Media.
Worden said he began planning a solar boat in earnest about four years before the report. He wanted to design a zero-emissions vessel from the ground up rather than adapt an existing boat. The TruSolar40 is not presented as the first commercial solar boat: the report notes that a Coast Guard-approved solar-powered passenger boat began carrying people on the Hudson River in 2018. Such vessels remain uncommon.
Worden told Canary Media that he learned about commercial boating standards from a retired Coast Guard captain and began working with the Coast Guard before the final designs were completed. The report does not say that either Worden Marine model has received certification for commercial passenger service.
Sales and Certification Remain Open
Worden Marine has not announced a completed sale, named a customer or given a production timetable. It is also unclear what the two boats will cost, how soon the TruSolar40 could be ready for delivery, or whether either model has secured the approvals needed for commercial passenger operations.
The performance figures reported for the TruSolar20 come from a demonstration and statements by Worden. The report does not provide independent testing, range figures, battery capacity or data from regular service across different seasons and weather. The company’s expected configuration options and operating speeds may depend on the final build and use.
First Customers Will Set the Pace
Worden Marine is speaking with prospective customers, according to Worden’s account to Canary Media. The next concrete signs of progress would be a disclosed order, a production or delivery schedule, and details on the commercial approvals and operating arrangements for the selected vessel. The company has not announced dates for those milestones.
If discussions lead to orders, customer choices may shape the boats’ seating and equipment. Until then, the TruSolar20 remains a prototype and the TruSolar40 a developing design, with the startup’s commercial prospects still unproven.
Key Questions
What is Worden Marine developing?
The Massachusetts startup is developing the TruSolar20, a 20-foot solar-powered prototype, and the larger TruSolar40 for possible ferry, tour and recreational uses.
How fast can the TruSolar20 travel?
Canary Media reported that it cruised at about 5 miles per hour on solar power during a mostly cloudy day demonstration. Worden said it can reach 8 miles per hour on solar power in sunnier conditions and approach 14 miles per hour using battery power.
Has Worden Marine sold any boats?
Worden told Canary Media that the company had not closed any sales, though it was talking with several possible customers.
Is the TruSolar40 certified for commercial passenger service?
The report says Worden has worked with the Coast Guard on standards, but it does not report that the TruSolar40 or TruSolar20 has received commercial certification.
