We run an event at MIT every year called the Charles River Team Race. 24 teams, 36 boats. The format
we use starts with an initial round, with the teams randomly seeded, and then reseeds the teams after
each set. The final winner for the regatta is decided by which team accumulates the most "regatta points",
which are calcualted as described below. Beating a higher ranked team is worth more than beating a
The format is as follows:
Teams are randomly put into 4 groups of 6 teams. (A, B, C, D).
Each group sails a round robin within their group. (5 races/teaam)
They then rotate to the dock and groups C and D do the same.
At the end of this, each team in the regatta will have sailed 5 races. A team
receives 2 "regatta points" for each win in this round. (More on the points later)
The teams are then seeded based on their records, and split again into 4 groups of 6 teams. Group
A is teams seeded 1-6, B is 7-12, C is 13-18, D is 19-24. Ties are only broken if it is necessary
to determine which group a team will be in, and the tie breaker is based on
total "race points" accumulated by each team in the 5 races sailed to that point. (ie if team a beats
team b with a 1-2-3 vs 4-5-6, team a would get 6 race points, team b would get 15 race points)
If a tie remains after this, the tie is broken by a game of chance (coin flip, name from a hat, whatever)
Groups A and B now go back out and sail another round robin within their group. This will be another
5 races per team. A win in group A is now worth 4 points, a win in group B is worth 3 points.
A and B then switch out and groups C and D also sail a round robin against their group. A win in Group
C is worth 2 points, a win in group D is worth 1 point.
At this point, each team will have sailed 10 races, and will also have a "regatta points" total, which is the
total of the number of wins in round 1 times 2 + the number of wins in round 2 times the group weight (4 for A, 3 for B, etc).
The teams are now reseeded, based on their overall record for the event. (10 races so far). Ties are now broken
by the number of "regatta points", and then by the number of "race points" accumulated in each race the teams have
done. It is important to reseed based on record, not regatta points, as this would allow a team which incorrectly found themselves
in Group D (ie. they are a good team who fell on hard times) to go 5-0 and quickly move up to better competition. At 1 point
per win, if you reseeded on regatta points, a team in group D going 5-0 would still have a hard time moving up a group.
Once again, group A is teams 1-6, B is 7-12, C is 13-18, D is 19-24. The points awarded per win remains the same in
each group for the rest of the event (4 points for a win in group A, 3 for group B, 2 for group C, 1 for group D) Each
group again sails a round robin amongst their group.
This format continues until you run out of time, with the teams being reseeded after every set of round robins.
If you wish, you can end with a finals amongst the top group, with wins being worth more than 4 points. (we have used
5 points for this round, but it depends how much weight you want to put on the finals)
The end result is that teams end up sailing races against other teams of similar abilities. The top teams are the ones
who can maintain an above .500 record against the other .500 teams and clean up on the lower ranked teams should
they move out of the top group.
We do the scoring using Excel. The rotation is easy, as it is just a 6 team round robin which we take from the USTRA website.
