QUESTION FROM A FAN: How to divide fleets into divisions in a big regatta?

L18634_2 How to divide fleets into divisions in a big regatta?

QUESTION (from a race officer);
I have a question too: what computer programme is used for scoring boats on big Opti Events? The main option which we need - how to divide all boats to fleets and score them. In our country we use our programme but still we had not any Event there was need to divide boats in one class to fleets. But now this problem has risen. >Warmest regards.


ANSWER (by the blog editor);
Just for your reference, here are three samples of Sailing Instructions for big Optimist regattas.

Example 1: IODA World and North American Championship 2010

  Boats; about 200 boats for World and North American Champ each

SI 7. FORMAT OF RACING
7.2 Individual North American Championship (INAM)
(a) Divisions: The fleet will be divided into six divisions. Each division will sail with each other at least once. Attachment 3 shows the starting schedule.
(b) Identification of divisions: Each boat shall display a coloured ribbon corresponding to the colour of her division flag, permanently fixed and free to fly from the top of the sprit. The ribbons will be provided by the Race Office.
(c) Allocation to divisions: Boats will be sorted by alphabetical order of national letters and then by numerical order of the sail numbers. The first boat of the sorted list will be allocated a number between 1 and 6 to be drawn by lot and the rest of the boats will be allocated numbers in a sequential order, each number representing one division. (For example if the number for the first boat is 2, the first 8 boats will be allocated numbers 2, 3, 4, 5, 6, 1, 2, 3). The seeding will be done as soon as possible after the completion of the registration.
SI 19. SCORING
19.1 Race scores:
(a) Each race of two divisions will be scored as one race in which all competitors of those two divisions have entered. Allocation of points according to rule A4.2 will consider that ‘the number of competitors entered in the series’ is the maximum number of competitors after grouping the two largest divisions.
(b) For overall scoring purposes, a race will be defined as one completed race for all 6 divisions in the sequential numbering of races in Attachment 3. Only races that have been completed for all 6 divisions will be included in the series scoring.See ATTACHMENT 3: THE STARTING SCHEDULE

Example 2: SINGAPORE Optimist National Championship 2008
  Boats; about 180 boats

SI 6. FORMAT OF RACING
6.1 If the number of entries received for any class at the close of entries is less than 80, the regatta will consist of a single series for that class.
6.2 If the number of entries received for any class at the close of entries is more than 80, the regatta will consist of a qualifying series and a final series for that class.
6.3 For the qualifying series, the entire fleet will be divided into 4 groups: White, Yellow, Pink, and Brown. When more than 4 groups are required, appropriate measures will be taken. The seeding of boats into the 4 groups will be based on the current National Ranking where available or another method as determined by the Organising Authority. The seeding will be done as soon as possible after the closing of entries and shall not be subject to protest. This changes rule 60.1(b).
6.4 (a) Each race of the qualifying series shall consist of 2 groups racing together and where possible each group shall race each other group an equal number of times.
(b) Groups may be started in any order however the Race Committee will attempt to start as follows:
Race No.             Groups               Colours
Race 1A              1 & 2                   White & Brown
Race 1B              3 & 4                   Yellow & Pink
Race 2A              2 & 4                   Brown & Pink
Race 2B              1 & 3                   White & Yellow
Race 3A              1 & 4                   White & Pink
Race 3B              2 & 3                   Brown & Yellow
Race 4A              3 & 4                   Yellow & Pink
Race 4B              1 & 2                   White & Brown
Race 5A              1 & 3                   White & Yellow
Race 5B              2 & 4                   Brown & Pink
6.5 (a) Boats will be assigned to final-series fleets Gold, Silver, Bronze, Emerald, etc., on the basis of their ranks in the qualifying-series. The final-series fleets will have, as nearly as possible, equal size but so that the Silver fleet is not larger than the Gold fleet, etc. Boats with the best qualifying-series ranks will race all final-series races in the Gold fleet, boats with the next-best qualifying series ranks will race in the Silver fleet, etc.
(b) Any recalculation of qualifying-series ranking after boats have been assigned to final-series fleets will not affect the assignments except that a redress decision may promote a boat to a higher fleet.

Example 3: JAPAN Optimist National Championship 2010
  Boats; about 140 boats

SI 6. FORMAT OF RACING
(a) Divisions: The fleet will be divided into four divisions. Each division will sail with each other at least once.

(c) Allocation to divisions: Boats will be sorted by the current National Ranking and then by alphabetical order of the junior clubs’ names.
(d) Each race of the qualifying series shall consist of 2 groups racing together and where possible each group shall race each other group an equal number of times.
(e) Groups may be started in any order however the Race Committee will attempt to start as follows:
