Glosten and Bieker Boats have joined forces to bring modern composite hydrofoil technology to the passenger vessel community. This collaboration draws on Bieker Boats’ years of experience designing fast foil-borne boats – including leadership on Oracle Team USA – and Glosten’s design of passenger vessels for public and private clients over the past 50 years.
With a cruise speed of 35 kts and 2×515 kW horsepower, this ferry requires less than half the installed power of a typical passenger catamaran, resulting in a 50% reduction in fuel consumption. And when compared to the latest foil-assisted low-wake small passenger vessels, our design achieves three times the passenger miles per gallon.
We achieved this by combining the proven technologies of ultra-efficient hydrofoils, lightweight carbon fiber hull construction, and modern geared propulsion equipment. Battery electric propulsion can be provided for short routes (<15 nm), lowering the cost of operation even further.
Safety and Comfort
Safety of passengers and crew is paramount for all ferries. With the capacity to carry 150 passengers plus crew members, our design incorporates a foil collision energy absorption system designed to dissipate the energy during contact with a submerged object. Positive lift is maintained as the foil rotates upward during an impact, greatly reducing the overall acceleration experienced by the passenger.
Comfort is enhanced as the ferry flies over waves, rather than through. Transit times are also unaffected by rough water as speed (and fuel efficiency) is maintained.
The vessel’s hull is constructed using carbon fiber with foam cores above the waterline. This results in a significant weight savings over the lightest aluminum construction. The struts and foils are constructed of carbon fiber laminates, achieving the same strength and stiffness of high strength steel at 20% of the weight. These advancements in foil design and manufacturing can be seen in the latest America’s Cup foiling yachts.
