PY Look Alike
SCHRS is the principal handicapping system recognized by World Sailing for cat on cat racing. Where monohulls and catamarans race together in the UK, Portsmouth Yardstick (PY) ratings are commonly used. The PY Look Alike ratings below are provided to enable catamarans without official PY Ratings to compete.
The Portsmouth Yardstick Committee and SCHRS Technical Committee have agreed a conversion factor that may be applied to any make, model and configuration of catamaran for which an SCHRS rating has been approved by SCHRS so that it may be raced under the Portsmouth Yardstick. The conversion formula is SCHRS x 678 = PY and is shown in the column headed PY LOOK ALIKE.
To strengthen the SCHRS to PY conversion factor, UK clubs are encouraged to provide data to the RYA for all races in which catamarans compete. If such races are initially scored under SCHRS, sailing scoring programs such as Sailwave or HAL Race Results are capable of dual scoring under a second system such as PY. This would allow for results to be considered under both SCHRS and PY and the results of PY Racing to be simply uploaded direct to www.pyonline.org.uk, strengthening both schemes. For advice on dual scoring use scoring software help systems or contact RYA Technical and Racing Services.
