Handicap positions are worked out after the end of each race. The actual sailing, or elapsed, time for each boat is multiplied by its Time Correction Factor (TCF) to produce a Corrected Time. The lowest Corrected Time wins the race on handicap.

The race results are exhibited at the clubhouse as soon as possible after the race has finished and include the changes to TCFs for the next race.

For Open Handicap races, a Time Allowance in minutes will be calculated for each yacht. This Time Allowance is based on each yacht’s TCF and the average of average elapsed times of races sailed to date. These Time Allowances will be available in the clubhouse by 12 noon on the day of the Open Handicap race.

Wherever possible the pick-up boat will have a list of Time Allowances for Open Handicap races and TCF’s for Sealed Handicap races.

Handicaps for the start of the season will be an average of the last five scratch races sailed in the previous season.

Note that a TCF is attached to the combination of yacht and skipper. A change of skipper or a significant change in the yacht or its sails will cause it to start the next race with an adjusted TCF. It is the responsibility of the skipper to consult the Handicapper on what constitutes a significant change. An unreported significant change will be considered a breach of these sailing instructions.


Every yacht has a TCF. This is used to calculate its Corrected Time in a race and adjusted after each race to recognise the yachts performance. This adjustment produces a new TCF.

Following a race, a yacht also has a Performance Rating (PR). The PR is calculated from the yachts elapsed time (a), the average elapsed time (b) and the average TCFs of all the yachts that finish (c). The formula used is PR = [bxc]a.

The PR is used to adjust the TCF. The resulting number is the new TCF which is used for the next race.
