The UK RYA has just released its PY numbers for 2024 and I updated the table of HalSail standard handicaps this morning.
If you want to update your PY racing classes to the latest numbers, log into HalSail and go to Boats > Standard handicaps. Click the button showing your PY classes and you will see a table of boats and their handicaps. Those that are not in agreement with the latest numbers will be shown in red. Either update them individually, or click the button to update them all at once.
