Performance analysis

Prediction and optimisation of sailboat performance is at the heart of CRAIN know-how, helping sailboat designers to :

  • Study, design and optimise hull and appendage shapes
  • Study, design and optimise sail plans
  • Study of boat behaviour parameters as longitudinal trim, yaw, heel
  • Velocity prediction

For fifteen years, CRAIN has developed and confirmed numerical and experimental tools specifically adapted to sailboat studies. Its involvement in the most demanding race projects over the years guarantees quality tools and methods.

  • Parametrics formulas
  • CFD for hull and appendages (potential or viscous flow)
  • Tank testing
  • Wind tunnel test for appendages
  • CFD for sails
  • Wind tunnel test for sail plan and rig

Hydrodynamic and aerodynamic studies of the different parts of the boat provide the designer with useful quantitative and qualitative information for analysis and optimisation.

Exploitation of results is made possible by performance prediction software V2P, used and continuously developed by CRAIN since 1987.

Through the many studies carried out by CRAIN for designers, project manager, sailmakers and shipyards, CRAIN has the flexibility which allows it to propose the most adaptative approach to project targets, schedules and cost constraints.

CRAIN has gathered unmatched experience through various projects :

  • Cruising monohulls and multihulls
  • Oceanic and day racing multilhulls
  • Oceanic open monohull
  • IOR and IMS monohull
  • IACC boats
  • Megayachts and megaraces
  • Hydrofoiler and speed record sailboat

This experience allows CRAIN to :

  • Guarantee safe and comfortable behaviour of the sailboat (heel, balance, sail handling)
  • Optimise parameters of the project
