Cape Horn Engineering is an independent CFD consultancy company with vast experience in the design of sailing and motor yachts, commercial ships and in the renewable energy sector. We offer state-of-the-art expertise in flow analysis for improved performance and safer procedures. Our CFD methods cover a large variety of flow behaviours and includes free-surface flow, viscous flow, full-scale performance prediction, fluid-structure-interaction, dynamic behaviour and design optimisation. Cape Horn Engineering was established in 2007 and is now based in Portsmouth, UK. We are industry leaders in flow analysis with an expertise in aero-dynamic and hydrodynamic performance. Cape Horn Engineering are involved in the design and development of yachts for a wide range of high performance racing. Our methods have been developed in the extremely ambitious America’s Cup environment, which requires rigorous testing and validation to remain competitive at the highest level. Our designs have won 3 consecutive Volvo Ocean Races, with ABN Amro, Ericsson Racing Team and Groupama Sailing Team. Our flow analysis has been proven in a wide variety of other marine applications including superyachts, sailing yachts, power boats and high speed vessels. Our range of services within the maritime sector has expanded to commercial ships, including cargo ships, service operation vessels, work boats, and more recently the renewable energy sector including offshore platforms and wind energy structures. With new guidelines and regulations for ships to reduce emissions and improve air pollution, the demand for yacht and ship optimisation is a key requirement with yacht designers and naval architects. CFD analysis will support designs to improve efficiency and performance, including aerodynamic simulations for innovative solutions such as using wind propulsion technology.
