Notes on Performance Handicap Systems in Yachting
Performance Handicap Systems in yachting yield a handicap (a number) that enables yachts of varying speed potential to compete in races where the yacht with the least corrected time wins – where corrected time is elapsed time multiplied by the handicap. After a race, calculated handicaps are obtained from a set of rules applied after the standard corrected time of the race has been determined. This paper demonstrates new methods of determining the standard corrected time and calculated handicaps as well as reviewing some current methods.

Report on a Performance Handicap System for Windrush State Championships 2023
The 2023 Windrush (Yacht) State Championships were held on Geographe Bay, Western Australia at Dunsborough Bay Yacht Club (DBYC) in early March 2023. The Race Committee was interested in providing results from a Performance Handicap System (PHS) as well as the usual elapsed time order results and this report gives a detailed explanation of the PHS used to score the series.

Correcting times for different length sailing courses
To ensure that sailors are not waiting for long periods between races, faster yachts are assigned to fleet A and sail course A and slower yachts are assigned to fleet B and sail a shorter course B with the aim of all yachts finishing within a 5-10 minute period. If handicap race results are required for the combined fleet, then the elapsed times of yachts for fleet A sailing course A (the longer course) need to be scaled to represent times they might have had, if they had sailed the shorter course B. This paper (5 pages) sets out a plausible method for calculating scaled elapsed times for fleet A yachts.

Speed Sailing: Land Yacht Speed Record Attempt
The current world speed record for a land yacht is held by Richard Jenkins (UK) in Greenbird at a speed of 202.9 km/h set on 26-Mar-2009 at Ivanpah Dry Lake, Prim, Nevada USA. An attempt to better this record will be made by Emirates Team New Zealand in mid-2022. This paper (34 pages) sets out the methods and formula that will be used to determine the velocity of Team NZ’s land yacht using post-processed kinematic GPS observations.
