Rating Optimization

OVERVIEW

Wyspa Technologies provides consultation to owners and teams looking to elicit maximum performance from their boat on the race course. Rating rules are created to level the playing field between various designs to allow for fair and even competition. Winning races comes down to details and preparation, leaving no stone un-turned when you show up on the course for race day.

Services include 3D scanning hull geometry, polar generation, trial certificates, appendage design, sail size and inventory selection (in conjunction with a sail designer), and sailing performance analysis.

Rating Rules

IRC, ORC, and ORR are three of the major rating rules which take a variety of measurements and characteristics of each boat to develop a single number or set of numbers, across various conditions and angles, allowing race committees to equalize performance on the race course. IRC is based on an undisclosed formula using a simple set of hull and sail measurements along with a flotation and incline test. ORC and ORR require similar measurements along with a digitized representation of the hull form. Other rules, such as PHRF, need fewer measurements and also factor in past performance, these are referred to as handicap rules.

3d Scanning

A 3D scanner is used to generate the digitized representation of the hull form required for ORC and ORR. On the most basic level, a hull can be scanned and the necessary file generated for the local rating office to provide a rating for racing with no further optimization. The rating offices generally have these files preexisting for popular production racers, in which case a standard rating could be provided without the expense of scanning. To evaluate possible modifications and improvements, as small as weight shifts or sail choice through full appendage optimization, a 3D scan of the hull geometry is immensely valuable.
