SailTool is a program for the measurement and parameterisation of yacht sails and rigging. The program runs on PCs running Microsoft Windows and provides a user-friendly interface for performing high accuracy measurements.

Features include:

Camera requirements: The program can process images from any source e.g., digital cameras or scanned images from film cameras. Higher resolution images allow greater measurement accuracy – subject to operator accuracy.
Suitable Image Formats: PNG, JPG, GIF, BMP.

SailTool was originally developed by the Centre for Marine Science & Technology (CMST) for the Australian Yachting Federation for use in the coaching of the 2000 Sydney Olympics yachting team. A team that was successful in winning four gold medals.
