Two boats of similar size at the same speed in the same wind clearly gives an indication of stiffness. The stiffer boat heels less. In the example given, the Catalina requires more power to run the same speed because it has more drag. All else equal, we would expect the First 40 to heel less. Not sure how you could argue otherwise.

Here is the problem with your argument, the Catalina 40 is not just beamier, it is longer at the water line and fuller in the fore and aft body. And its got a hull design remarkably similar to the First 40 below the water line. Perhaps if you had ever seen these two boats out of the water, you would understand.

And of course the Catalina 40 is heavier. Not sure how you could argue a First is stiffer. Perhaps you should look at the RM diagrams to convince yourself.
