Handicapping Changes for 2020

1. NFS-Delta - Jamie Dike

• In 2012 PHRF-LO introduced a new NFS offset
  • Work done by Jim Teeters / US Sailing
    • Coefficients that use: Sail Area / Displacement, Displacement / Length ratios
  • A General Purpose Handicap was applied fleet wide
• After five years of data it was clear a review was required
  • Proposed the use WL10 (windward/leeward course at 10 knots)
  • This was rejected by handicappers for the “odd” results it created & was dropped pending further study
• Proposal – Use WL8
  • Wind study provided the basis using 8 knots of windspeed
  • Applied sailing displacement as part of calculation

Improved sail area data has refined results as well

Preliminary Draft for review at: Revised: Feb 25th
