Vessev develops electric hydrofoil ferry for efficient water transport

Vessev's VS-9 Electric Hydrofoil

Vessev has introduced the VS-9, an electric ferry that utilizes hydrofoil technology. The vessel, approximately 30 feet in length, incorporates two wing-like structures beneath its hull. These hydrofoils lift the boat as it moves through the water, reducing the hull's contact with the surface.

Efficiency and Ride Quality

By lifting the hull clear of the water, the VS-9 operates with greater efficiency compared to traditional boats of similar size. This efficiency is crucial for electric vessels, as it maximizes the use of battery power. Computer-controlled underwater flaps contribute to a smooth and stable ride, preventing the bouncing and slapping common in conventional boats at speed.

In-House Manufacturing

Vessev manufactures the electric motor for the VS-9 in-house. According to CEO Eric Laakmann, this approach helps manage costs and integrates production earlier in the development process. The company sources batteries externally, as they are considered a commoditized component.

Hydrofoil Applications and Limitations

Hydrofoils offer advantages such as lower drag and a smoother ride, making them suitable for specific waterways like lakes, rivers, and bays. However, their effectiveness is limited by wave height; if waves exceed approximately 2.5 feet (0.75 meters), they can impact the hull, disrupting the smooth ride and reducing efficiency. This makes them less ideal for open ocean conditions.
