Shortening or abandoning after the start32 Shortening or abandoning after the start
32.1 After the starting signal, the race committee may shorten the course (display flag S with two sounds) or abandon the race (display flag N, N over H, or N over A, with three sounds), as appropriate,
(a) Because of an error in the starting procedure,
(b) Because of foul weather,
(c) Because of insufficient wind making it unlikely that any boat
Will finish within the time limit,
(d) Because a mark is missing or out of position, or
(e) For any other reason directly affecting the safety or fairness of The competition,
Or may shorten the course so that other scheduled races can be sailed. However, after one boat has sailed the course and finished within the time limit, if any, the race committee shall not abandon the race without considering the consequences for all boats in the race or series.
32.2 If the Hon. Starter signals a shortened course (displays flag S with two sounds), the finishing line shall be,
(a) At a rounding mark, between the mark and a staff displaying flag S;
(b) At a line boats are required to cross at the end of each lap, that line;
(c) At a gate, between the gate marks.
Every effort shall be made to finish the course on the usual start/finish line.
A course can be shortened when boats are only a few yards from the finish if the wind dies but should try to give as much time as possible to allow for change of tactics.
