I'm dreaming about my next boat and I have a few questions about estimating performance. What is the best way to estimate how a particular model boat will perform, is it PHRF numbers or numbers from Sailcalc like SA/D, LWL, Hull Speed, Motion Comfort, etc.?
The reason I ask is that for some similar boats, the numbers are kind of crazy. For example, consider the Beneteau 36.7 and the Beneteau 361. The numbers from Sailcalc are very similar
