an initialism for “on the course side.” The scoring abbreviation used to indicate that, at a boat’s starting signal, some part of her hull, crew, or equipment was on the course side of the start line and she either failed to restart properly or violated Racing Rules of Sailing 2013 – 2016 rule 30.1. The boat has the maximum points allowed assessed against her when the race is scored using a Low Point System. The maximum points allowed may be different for an individual race than for a race that is part of a series longer than a regatta. See Racing Rules of Sailing 2013 – 2016 Appendix A11. The applicable Notice of Race or Sailing Instructions may also modify the number of points assessed. Replaced the PMS ruling.
