UK designed foiling fast ferry enters build phase

Currently being built by Southampton composites specialist Designcraft the vessel - a high speed electric trimaran - is being  developed with £1.86m of Innovate UK funding, as part of an effort to decarbonise short coastal journeys and reduce costs for ferry operators. 

The project team also includes Solent University and sustainable marine engineering consultant Newcastle Marine Services . 

Whilst the ultimate aim is to develop a much larger vessel for commercial operation, the initial 10-metre demonstrator will feature a single fixed main foil, with the foiling and flight control carried out by a single foiling rudder. The design enables the TriFoiler to foil with less power than either a monohull or catamaran-based design, offering commercial ferry operators a cost-effective option for building and operating the vessel.

Capable of reaching 18 knots, the demonstrator vessel is powered by twin 20kW motors with 60kWh battery capacity and can accommodate three people. The batteries are positioned out wide on the craft, away from the passenger and crew area to enhance safety and maximise usable space.
