SailPack - Aero Results


SailPack-Aero is fast. Results are obtained within 2 to 4 seconds, allowing you to adjust your trim and shape in real time on both your rig module and your sail shape module.

The results may be viewed through the use of a fully interactive 3D graphic model (showing both high and low pressure as a separate surface) or interpreted through a results grid, including:


  • Lift Coefficient
  • Drag Coefficient
  • Driving force
  • Side force
  • Heeling moment
  • Area of reference
  • Fore & aft centre of effort position

Also shown are the detailed data results of each aerodynamic slice.

The graphic representation allows you the ability to easily see any quality of flow and identify possible stall or luffing zones. The vertical distribution of the pressure field is also shown.

SailPack - Aero 2D Study


This tool is very useful in achieving a better understanding of the overall working and aerodynamic outcome of any given sail plan. SailPack-Aero allows you to study each slice in 2D. You can select any slice and modify the treatment of each sail including angle of attack.

The impact of any adjustment made on one slice of one sail can immediately be visualized on both sail profiles:


Commercial Value

The 2D and 3D application and graphics, within SailPack-Aero, are very useful to demonstrate flow and help show the previously “invisible” effect of flow. As a result, above and beyond the analysis value of SailPack-Aero is the strong commercial value of both the 2D and 3D graphics when used in any visual presentation (seminar) or lecture situation.

SailPack-Aero has been designed to be versatile and, with modification (wing/mast effect), able to be integrated with other software such as “Relax 2” structural analysis software.
