Our Services

Cape Horn Engineering offers solutions to a large range of flow problems in:

  • The yacht design community,
    • High performance sailing boats read more..., mega yachts, classical yachts, Olympic classes, mono-hulls, multi-hulls
    • Motor yachts of all sizes and speeds
  • The marine industry in general
    • Advanced and unconventional vessels: wave-piercing catamarans, hydrofoils, SWATH, trimarans, hybrids, etc
    • Conventional vessels: cargo ships, container ships, bulk carriers, tankers, ro-ro's, passenger ferries, etc
    • Naval combatants, above and under water
  • The offshore industry
  • Research programs

Hydrodynamic investigations

Performance prediction in calm water

  • Full scale
  • Friction and pressure forces and moments
  • Dynamic sailing attitude, sinkage and trim
  • Wave resistance, wave breaking and spray resistance
  • Propulsion modeled at different levels of complexity

Performance prediction in regular waves

  • Added resistance
  • Global and local loads on structures
  • Slamming, green water on deck, sloshing, and more

Appendage hydrodynamics and optimization

  • Rudders, dagger boards, fin keels with or without tabs, bulbs, winglets
  • Spray rails
  • Trim tabs, interceptors and wedges
  • Hydrofoils
  • Stabilizers

Special investigations into the dynamics of wave and structure interaction

  • Motions in waves of dock-well vessels with sloshing in the dock-well
  • Floating breakwaters interacting with waves in shallow water
  • Propulsive characteristics of flapping foils, controlled bow-wings to reduce added drag

Flow investigation on special topics:

  • Analysis of breaking waves and sprays
  • Slamming and green water loads
  • Sloshing in tanks
  • Squat of large vessels in extreme shallow water

Aerodynamic investigations

  • Flow over sails and rigs, 'flying shapes'
  • Sail coefficients for all type of sails and rigs in upwind and downwind conditions
  • Sail shape optimization though parametric studies or genetic algorithm optimization
  • Air flow around hulls, decks, and superstructures (forces, moments, windage)
  • Structural (wind loads on superstructures)
  • Ship Helicopter Operating Limits (SHOL)
  • Occupant safety and comfort including local wind effects on passengers, exhaust gas, and cabin ventilation
  • Engine room and cargo hold ventilation
