Chine is just one element of boat design. A boat's performance is a function of how all of the different design elements work together. You cannot just look at "chine" or "no chine" and expect to tell anything about the boats overall performance.
And then, of course, there is the question of what the word "performance" means to you. Are you talking about performance on a lake with moderate winds? Performance far offshore
in heavy weather
? Something completely different? These are all different sorts of "performance."
The Flicka has a displacement
that is four and a half times as much as the Potter (assuming you're talking about a Potter 19). Heck! The Flicka's ballast alone is 37% more than the total displacement
of the Potter. The Potter's SA/D ratio is almost 18.5 while the Flicka's is less than 13. Their respective D/L ratios are 116 for the Potter and over 400 for the Flicka.
These are dramatically different kinds of boats. The Potter is going to run away from the Flicka in any sort of light-air condition, and in fact in most sailing conditions. The Flicka is going to sail far more comfortably in anything resembling heavy weather
, not to mention that it has the carrying capacity for much, much longer cruises.
So the bottom line is that there really is no comparison between these boats. If you are trying to understand the difference that a chine makes in a boats design, you really need to compare two boats that are fairly similar in other regards--where chine vs. no chine is the main difference between them. With these two boats that is just not at all the case.
