Revolutionary Invention

What is the Y-Hull®?

Y-Hull® is a hybrid hull form that intelligently combines the best characteristics of two established hull types — creating something entirely new and patented.

🌊
Reduced Wave Resistance

Y-Hull® substantially reduces bow-induced waves, lowering hydrodynamic resistance as the ship moves forward through water.

25% Fuel Efficiency

Technical analysis, along with practically proven data from operational vessels, demonstrates significantly less resistance compared to traditional monohulls and catamarans — directly translating to a 25% reduction in fuel consumption compared to a similar monohull.

💨
Auto Air Lubrication

The unique Y-Hull® shape automatically allows air to flow underneath the hull from bow to stern. This natural air layer between the hull and water surface reduces frictional resistance — a passive, maintenance-free efficiency gain with no additional systems required.

🔀
Hybrid Hull Form

Integrates the structural and economic advantages of a monohull with the stability and speed of a catamaran in a more efficient way — addressing a long-standing compromise in naval architecture.

🌍
IMO Net-Zero Aligned

Y-Hull® directly addresses GHG challenges in maritime engineering, supporting IMO targets for net-zero emissions from international shipping.

🔬
Peer-Reviewed Research

Supported by a peer-reviewed RINA 2019 conference paper and backed by five years of independent research (2014–2019) by the sole inventor and patent holder.

The Journey

From Research to Reality

The Y-Hull® represents five years of dedicated independent research, progressing from concept through rigorous CFD testing to a granted patent and two operational vessels.

2014
Research Begins

Independent research initiated by Amitavo C Wye — identifying inefficiencies in existing hull forms and conceptualising the Y-Hull® solution.

2017–2018
CFD Simulation & Testing

Extensive CFD simulation using Simcenter STAR-CCM+, model testing, and hydrodynamic analysis — including validation of the auto air lubrication effect.

2019
Patent Granted

Singapore IPOS Patent No. 10201901198Q granted. Peer-reviewed paper presented at RINA 2019 International Conference.

2020–Present
Commercial Deployment

Two operational Y-Hull® vessels built and deployed. Licence agreement with EcoNavis Solutions Ltd. for UK and European commercialisation.

Hull Form

The Y-Hull® Geometry

The defining feature of the Y-Hull® is its unique cross-sectional profile — twin forward demi-hulls that gradually merge into a single stern hull with single-shaft propulsion. This geometry creates the natural air channel that gives Y-Hull® its exceptional efficiency advantage.

Designed, analysed and validated across a comprehensive CFD simulation programme using Simcenter STAR-CCM+, covering multiple Froude numbers and displacement conditions.
