Our boat (37.5 Legend) has been PHRF rated at 102 on Lake Erie. We are sailing her well and within a few boatlengths of Tartan 40's and a C&C 44. I need some baseline data such as Performance Prediction data (including polars if available) for tuning and measuring overall performance. And, of course, trying to capture some hot info for best speed on various tacks w/ conditions.
