Description of the Invention
What is the Y-Hull®?
Y-Hull® is a hybrid hull form that intelligently combines the best characteristics of two established hull types — a monohull and a catamaran — creating something entirely new, patented, and commercially proven.
Y-Hull® substantially reduces bow-induced waves, lowering hydrodynamic resistance as the ship moves forward. This directly reduces the power required for propulsion.
The unique Y-Hull® geometry automatically allows air to flow underneath the hull from bow to stern — creating a natural air cushion that reduces frictional resistance with no additional systems required.
Technically analysed and practically proven — Y-Hull® demonstrates significantly less resistance compared to both traditional monohulls and catamarans, directly translating to 25% fuel savings.
Twin forward demi-hulls converge into a single stern hull with single-shaft propulsion — combining structural efficiency, stability, and hydrodynamic performance in one patented design.
Y-Hull® directly addresses GHG challenges in maritime engineering, supporting the IMO's strategy for net-zero emissions from international shipping by 2050.
