Hi Pipo,
You say:
"I can go back to the basics and measure myself against other sailors and if I loose, there will be no excuse."
Sounds like you want "One Design" racing.
If you live in the UK and if your crew weight suits F16HP, you can combine One design and Formula racing. You might find that the Spitfire suits your needs - a grandfathered F16HP and a class that had 16 cats at the Grafham Water Inlands last month.(15 raced).
