CFD Specialists & Marine Technology Solutions

Cape Horn Engineering, is a UK-based, independent Computational Fluid Dynamics (CFD) consultancy trusted by clients worldwide. We lead the field in yacht & ship design optimisation, delivering practical, high-impact solutions for racing yachts, commercial ships, superyachts, and renewable energy projects.

Led by Dr.-Ing. Rodrigo Azcueta (Managing Director and naval architect with +20 years of experience), our team has powered multiple America’s Cup campaigns and dominated the Volvo Ocean Race for nearly a decade,  helping three sailing teams win the iconic “Around the World” race.

Our CFD Services

Cape Horn Engineering specialises in high-fidelity performance prediction for racing yachts, sailing yachts, superyachts, motor boats, commercial ships, service operation vessels, and renewable energy structures.

What is yacht & ship design optimisation?

It is the data-driven process that uses Computational Fluid Dynamics (CFD) to simulate how water and air interact with every surface of a vessel. Each iteration refines the hull, appendages, foils, sails and propulsion, converging on the ideal balance between speed, efficiency, comfort and regulatory compliance.

Key benefits our clients see:

  • Significant fuel and emissions savings (often 5–15 % depending on the vessel)
  • Measurable improvements in EEXI/EEDI ratings
  • Faster, more stable and safer designs
  • Reduced need for expensive physical tank testing

Our methods handle free-surface flow, viscous flow, full-scale Reynolds-number predictions, fluid-structure interaction and dynamic behaviour.

We deliver clear, actionable insights that naval architects, yacht designers and ship owners can use immediately. Our passion, attention to detail and exclusive access to the best CFD tools ensure every project gets outstanding, real-world results.

SHIP DECARBONISATION & EEXI/EEDI

Cape Horn Engineering uses specialist CFD to help shipping fleets cut emissions and meet IMO rules. We deliver fast, regulatory-grade EEXI and EEDI calculations alongside hull optimisation and Energy Saving Device (ESD) analysis, covering ducts, fins, propellers, and wind-assisted propulsion, validated with leading classification societies, including Lloyds Register.

Key benefits: reduced fuel consumption, improved EEXI scores and clear comparisons of design and retrofit options.

SHIP DESIGN OPTIMISATION

Cape Horn Engineering has pioneered RANSE-based CFD for two decades. We now apply the same proven racing technology to commercial ships, cargo vessels, SOVs, CTVs and work boats.

The result is  more energy-efficient hulls and appendages that reduce fuel and emissions while improving safety and comfort in real sea conditions.

What you gain: faster design iterations, lower project risk and full-scale performance you can trust.

RENEWABLE ENERGY STRUCTURES

At Cape Horn Engineering we combine our expertise in aerodynamics and hydrodynamics to optimise wind-energy rotor blades, wave-energy converters, floating platforms and their support vessels. We make Service Operation Vessels (SOVs) and Crew Transfer Vessels (CTVs) more efficient and reliable in harsh offshore environments, lowering their carbon footprint at the same time.

Key outcomes: higher energy capture, better stability and faster project deployment.

SUPERYACHT DESIGN OPTIMISATION

For over a decade Cape Horn Engineering has worked hand-in-hand with the world’s top superyacht designers and builders. Using detailed CFD we ensure every project achieves outstanding performance, comfort, stability and safety.

A genuinely green approach involves cutting fuel use and emissions without compromising luxury or style.

What our clients value most: early-stage optimisation, real-wave seakeeping analysis and stunning flow visualisations for both engineering and marketing.

YACHT DESIGN OPTIMISATION

Cape Horn Engineering continues to push RANSE-based CFD boundaries every day. Our racing pedigree lets us optimise sailing yachts, power boats, foiling vessels and unconventional designs for real-world performance.

We simultaneously save fuel, reduce emissions, increase speed and improve comfort and safety.

Typical results: refined hulls and foils, accurate full-envelope predictions and confident design decisions.

YACHT RACING DESIGN

Cape Horn Engineering has been at the core of simulation based America’s Cup and Volvo Ocean Race design campaigns for over 15 years, always pushing the boundaries. Our designs and engineering solutions have helped three sailing teams win the famous ‘Around the World’ race. We are still involved with designing IMOCA Open60, multi hulls and high-performance racing yachts. We can help you win races.

Our Sail Design Service

aerosim top header

Our online CFD computations are for sail makers, naval architects and yacht designers.


Using state-of-the-art aerodynamic CFD and high-fidelity simulations, we optimise your sail designs and the overall boat performance in a matter of hours, not weeks.


We analyse single sails, complete inventories, multiple wind angles, weather conditions and full racecourse scenarios. You receive accurate performance rankings plus detailed visualisations of sail loads and flow behaviour, all ready for immediate use in your design or marketing materials.
