The Queen Mary System revealed.
Posted on June 12th 2011, by Pauline Penny
The Queen Mary system is a means of scoring where helms can quickly get into the top set but then still have to work hard to get into the top 3 and stay there! Basically points are awarded for beating other boats that are ahead of you or are close behind in the overall league. How close behind is determined by the average turnout so far plus an arbitrary factor - the latter being decided at the start of the season or series.
In the late 80’s points were calculated and score sheets filled out by hand. Later a program was written, by David Alexander, to automate this to some extent. It is now desired that the scores are placed on the Internet to make them more accessible to club members and to promote the QM system in general.
I took on this challenge and late in 2010 produced an Excel version of the QM system based on formulas only. However talking to various people it became clear that there were different interpretations of the ’system’. To this end I have put what I now know down in good old black and white for your perusal and to promote discussion or eventually come to a consensus.
I believe that Phil is also involved in developing a new system for all fleets. that would make the Excel version obsolete but the system described below, once ratified, would still apply!

Average Turnout
============
The average number of boats per race can be calculated in one of several ways including:
- at the end of the previous days racing.
- after an individual race
- before an individual race
- on completion of today’s racing
=Boats Turned Out So Far / Total Races So Far.
Rounding can be applied here to give a whole number or can be applied later after calculating the Handicap.
Handicap Factor
=============
A low factor (under 1) favours lesser sailors but who sale frequently to build up points. A factor above 1 favours sailors who often win but who sail less often. BSC has, I believe, used a Handicap factor of 0.8 for a number of years. Although a HF of 1.0 was used in 1988 when Stan Hackney typed up his notes and examples.
Handicap
========
Handicap = Average Turnout x Handicap Factor
In practice how Average Turnout is calculated and when & where Rounding is applied does not affect scoring greatly. Someone has to win and as long as we all play by the same rules it matters little.
Scoring Points
============
A - Each boat starting the race is awarded 1 point for turning out.
B - Each boat disqualified loses its starting point (i.e. scores zero).
C - A boat retiring scores an additional 1 point off each disqualified boat that at the start of the race…….H.
D - A boat that finishes the race scores 1 point off every boat that it beats (including Retired and Disqualified) that at the start of the race has a total points score equal to or greater than (the boats score minus the Handicap).
E - DNS a helm/crew that Did Not Sign is effectively disqualified from the race. See club rules in the handbook.
F - There is no minimum number of boats to form a quorum. One boat finishing the course and not being disqualified will be awarded the one starting point only - there being no other boats to beat!
