Handicap Systems Guide

When running mixed-fleet racing with corrected time scoring, you need to choose a handicap system. Each system uses a different method to adjust finishing times so that different boat types can race fairly against each other.

Available Systems

PY (Portsmouth Yardstick)

The most common handicap system for UK dinghy racing. Maintained by the RYA.

  • How it works: Each boat class has a PY number (typically 900-1500). Lower numbers = faster boats.
  • Corrected time formula: Corrected Time = (Elapsed Time × 1000) / PY Number
  • Best for: UK club dinghy racing
  • Note: If your club submits PY returns to the RYA, see RYA PY Online Integration

IRC (International Rating Certificate)

An international keelboat handicap system using a secret formula maintained by the RORC Rating Office.

  • How it works: Each boat has a TCC (Time Correction Coefficient) based on measurement data
  • Best for: Offshore and keelboat racing

ASY (Australian Yardstick)

The Australian equivalent of PY, used primarily by Australian sailing clubs.

  • Best for: Australian club racing

CYCA (Cruising Yacht Club of Australia)

A handicap system specific to the Cruising Yacht Club of Australia.

  • Best for: CYCA events and affiliated clubs

ECHO

A handicap system used in the UK for keelboat racing.

  • Best for: UK keelboat club racing

NHC (National Handicap for Cruisers)

SCHRS (Small Catamaran Handicap Racing Scheme)

A specialist handicap system for catamaran racing.

  • Best for: Catamaran fleets

YTC

A yacht handicap system.

Choosing a Handicap System

The right choice depends on: 1. Your country - PY for UK, ASY for Australia, etc. 2. Your boat types - dinghies, keelboats, catamarans, cruisers 3. Your governing body - some require specific systems for official results

Most UK dinghy clubs will use PY. If you're unsure, check with your national sailing authority.
