Wind+Wing Technologies

What Wind+Wing Technologies does

Wind+Wing Technologies is a privately held marine technology company founded in 2014 and headquartered in Napa, California. The company develops autonomous hard-wing sail systems that harness wind power to supplement vessel propulsion, targeting two distinct maritime segments: passenger ferries (via the WingDrive™ product) and commercial shipping (via the Cargo Wings™ product). Its underlying technology consists of proprietary hard-wing sails with computerized control systems that automatically harvest wind energy, demonstrated on two San Francisco Bay test vessels (a 42-foot trimaran in 2014 and a 10m all-electric catamaran in 2017) with claimed fuel savings of 10%–60% depending on configuration. WingDrive is marketed as a hybrid or zero-emission system for passenger vessels, while Cargo Wings is a modular, container-foldable unit designed for retrofit onto existing commercial ship or barge fleets.

The company operates a direct enterprise sales motion, with custom-engineered units made to order for individual client and route requirements; pricing is quote-based and not publicly disclosed. Revenue mechanics rest on three streams: hardware sales of WingDrive and Cargo Wings units, plus engineering and consulting services for route-specific deployment. The company has historically been funded through California state grants (CARB Air Quality Improvement Program, BAAQMD) and the founder's own resources rather than institutional venture capital, and no revenue or headcount figures are disclosed. Strategic positioning leans heavily on regulatory tailwinds (IMO 50% CO2 reduction target by 2050, low-sulphur fuel mandates), independent validation from UC Berkeley Transportation Sustainability Research Center, and a pending international patent application for wind-assist ferry technology. Named commercial activity is concentrated in the San Francisco Bay ferry ecosystem, with one planned 90-passenger electric WingDrive vessel project as the primary forward-looking commercial reference.

Core offering

Wind+Wing Technologies designs, manufactures, and sells autonomous wind-assisted propulsion systems for marine vessels. Its primary products are the WingDrive™ hybrid wind-assist system for passenger ferries and the Cargo Wings™ modular wing units for commercial shipping fleets. The systems automatically harness wind power to reduce fuel consumption and emissions, with custom-engineered units made to order for individual client and route requirements.

Product overview

Wind+Wing Technologies offers two core wind-assist propulsion products: WingDrive™ for the passenger vessel/ferry market and Cargo Wings™ for the commercial shipping industry. WingDrive™ is an autonomous hybrid system that reduces fuel consumption by up to 40%, while Cargo Wings™ provides modular wing units designed to fit standard shipping containers for installation on existing commercial vessels. Both products leverage the company's proprietary hard-wing sail technology that automatically harnesses wind power and transforms it into propulsion.

Functional benefit

Brands

• WingDrive™: A fully autonomous hybrid wind-assist system for passenger vessels that allows vessels to scale back fuel consumption and decrease expenses by up to 40%. Scalable to all vessel sizes, can be combined with hull propulsion for hybrid or zero-emission applications.
• Cargo Wings™

Products and services

• WingDrive™ Fully autonomous hybrid wind-assist propulsion system for passenger vessels (ferries) that automatically harnesses wind power and converts it into vessel propulsion. Reduces fuel consumption and operating expenses by up to 40%. Scalable to all vessel sizes and combinable with hull propulsion systems for hybrid or zero-emission applications.
• Cargo Wings™ Autonomous hard-wing sail units re-packaged to fold in and out of a standard 40' shipping container for installation on existing commercial ship or barge fleets. Modular design delivers minimum 10% fuel savings (up to 30% with optimized design) and converts capital expenditure into an operational expenditure model for shipping operators.
• Engineering & Consulting Services Technical consulting, route-specific wing deployment design, installation engineering, and operational optimization services for ferry operators and commercial shipping customers adopting WingDrive or Cargo Wings systems.
