Handicap Lists & Pursuit Race Calculator

Your club's handicap lists are visible on the public website, along with a pursuit race calculator tool.

Public Handicap Lists

Visitors can view your club's handicap lists at:

/clubs/{slug}/handicap-lists

Each list shows: - The handicap system used (PY, IRC, etc.) - Class-by-class handicap values - Summary information

Pursuit Race Calculator

The pursuit race calculator is a tool for working out start time intervals for pursuit (staggered start) races:

/clubs/{slug}/handicap-lists/{list-slug}/pursuit-race-calculator

In a pursuit race, slower boats start first and faster boats start later, so that in theory all boats finish at the same time. The calculator reads the rating system on the selected list and works out the correct order automatically:

  • For systems where a higher number means a slower boat (e.g. PY, ASY, YTC, SCHRS), the highest-numbered class starts first.
  • For systems where a higher number means a faster boat (e.g. SRS, IRC, ECHO, NHC), the lowest-numbered class starts first.

How to Use the Calculator

  1. Navigate to the handicap list you want to use
  2. Click Pursuit Race Calculator
  3. Set the start time of the first boat and the race duration
  4. Pick a class and click Add to race — repeat for each class taking part
  5. The Start Times table updates instantly, listing each class with its handicap and calculated start time, ordered earliest-first
  6. Remove a class with the Remove link to recalculate the remaining fleet

Start times recalculate automatically whenever you change the start time, duration, or the set of classes — there is no submit step. The reference boat (the one starting at the chosen start time) is determined by the rating system, and every other class is delayed by duration × (1 − relative speed) so the fleet should converge at the finish.

Standalone Pursuit Race Calculator

A standalone pursuit race calculator is also available at /resources/portsmouth-yardstick/pursuit-calculator. It works the same way but uses the national RYA PY numbers instead of a club handicap list, making it useful for ad-hoc race planning without needing a club account.
