Polar Diagrams

Does anyone know of a good resource of polar diagrams for older boats? I am trying to find one for my Pearson 32, without shelling out $300 to USSA.

Thanks!

Polar diagram Beneteau First 45f5

I'm desperately looking for the polar diagram of the Beneteau First 45f5. Unfotunately I'm not able to build up the polar diagram myself, since the boat is located in Hong Kong and I'm living in the Netherlands. In april, we are going to sail the Rolex South China Sea regatta and therefore I would like to have the polar diagram to use it with Raymarine RNS..

Thanks in advance,
Jurgen
