Re: Blue Jacket 40 (new racer/cruiser)
The stiffness of a boat is not measured by the smaller or bigger heel angle that is needed for a sailboat to sail at a given speed.
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.
Anybody knows that narrower boats will need more heel angle to sail than beamier boats but that does not mean that the beamier boat would be more stiff.
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.
