Offshore Foil Boats
Amphfoil Offshore Foil Boats are based on a new patented marine technology for high-speed (70mph/112kph), long-range (500nm/926km) performance propelled by hybrid electric creating breakthrough offshore vessels.
​
Amphfoils are groundbreaking super boats patented in 38 developed countries that redefine maritime travel with a unique blend of hydrodynamic and aerodynamic technologies. These hybrid electric boats engineered by Shannon Boat Company with over 40 years of marine expertise shatter conventional limits with high speeds and long distance range.
A First in the Global Marine Industry
High Speed Capability and Immunity to Rough Seas
​
The Amphfoil’s revolutionary technology combines the use of catamaran stability, surface effect lift, hydrofoil lift plus electric tilting air propellers for dual-purpose lift and propulsion to create a totally new type of efficient offshore foil boat. Amphfoil technology overcomes the massive shortfalls that have plagued conventional boats, catamarans and hydrofoils for decades. Amphfoils have unheard-of speeds and unmatched open ocean, long-range ability utilizing the latest 21st Century low emissions hybrid electric propulsion that requires 75% less energy.

The Amphfoil project has begun at Shannon Boat Company. In this short video, Amphfoil's naval architect and CEO Walt Schulz explains why Amphfoils are the first foil boats to use three distinct types of lift technology.
Today, the ability to ship nationally and globally is a major issue

In the video, Bill Ramos details the innovative approach taken by Shannon Boat Company to overcome the logistical challenges of shipping oversized vessels even short distances. He explains how Amphfoil models have been meticulously engineered to fit inside standard shipping containers, allowing for cost-effective and efficient global distribution. This design not only simplifies transportation but also facilitates easy assembly upon arrival, ensuring that the boats can be put into service quickly and with minimal labor.
