whilst on the subject of handicaps its goes against my grain but it would seem the PY systems have one advantage and plenty of disadvantages over SCHRS , in that py would recognise that f16 solo and two up travel at the same speed , this is widely accepted and proved by the fact that f16s allow solo and two up to race on equal footing , py should on returns hcap both the same (won't happen in uk as most folks race on SCHRS - which otherwise is much better and there will never be enough returns to calculate )
SCHRS as its a measurement rule can't correct this anomily ,although Scooby et al is working on it slowly , the righting moment element has helped albeit very small .
This anomily affects all solo sailors in schrs and f16 is a good case as it highlights the penalty on solo sailors , who are allready handicapped by having only two hands !
