Foil Optimised Stability System (FOSS)
Significant fuel savings and superior seakeeping
The benefits of foiling don’t always mean raising the hull clear of the water at speed.
To achieve significant fuel saving and superior sea keeping in a way that is suitable for adaption to a wide range of vessels, with differing lengths and multiple markets.
Its clear that one definitive solution does not fit such a broad range of leisure and commercial vessels and so a flexible approach is necessary. This method can then be adopted to enable BAR Technologies to help multiple clients. Meeting this challenge is only achievable with the complete range of knowledge, skills and expertise uniquely present within a single team at BAR Technologies.
Combining our latest hull and foil optimisation techniques, blended machine learning-based optimisation approaches, advanced parametric modelling and world-leading CFD simulation with bespoke mechanical component design, control logic and system design we developed a solution
Foil Optimised Stability System (FOSS)
The BAR Technologies Foil Optimised Stability System (FOSS) is an active ride control system designed to reduce fuel consumption and improve seakeeping performance using hydrofoil technology.
The use of active foils provides the following handling and comfort advantages:
- Reduce fuel consumption.
- Increased top speed.
- General motion damping.
- Active roll and trim response.
- Roll response in turns.
- Decoupling the effect of roll and yaw in quartering seas.
Our patented FOSS (Foil Optimisation and Stability System) makes it possible to achieve significant hydrodynamic efficiency gains whilst actively improving dynamic handling and sea keeping. From general motion damping, to active roll and trim response that can counter sea state and loading conditions, the most common comment from those that have experienced boats with our FOSS technology is that the vessel ‘feels glued to the water’s surface’ whatever you do. Particularly impressive is the system’s ability to decouple the effect of roll and yaw in quartering seas which significantly reduces broaching behaviour and increasing control
