If you notice the small, approx 2" wide, chine on the Euro of the 24, that is basically an extension of the same chine that is one the 23. Look on trader or some other site at a rear shot of the 32' and it is the same only wider.
It is my contention that euro's, if designed properly, ride better than a bracket, and can be more stable on the drift, becuase of this. I have stated it here before, many people disagree, the brakets do not extend the running surface but euros can. Look at any of the magazine ads of boats up on plane and notice how the water shoots up right behind the transom, and figure the ad boats are typically at max speed, imagine the lift force at the transom area. This is why boats with brackets propoise more. Look at all of the discussions on the 26 Reg with the F225's versus the 200HPDI, or why Grady extended the running surface on all of there euros after a few years.
That large, in the case of a 32', flat area acts like a stationary trim tab in a way, where as with a bracket as you come over waves, the water shoots up from behind the boat will the weight of the motors are 2' behind. The extended chine has to help support some of the additional weight. Just my thoughts.

Look at the 34 venture, 32 reg 28 hydra-sport, the list goes on they all try to extend this area while stepping up the center slighly for clean water. I know that on our old 27 Whaler with a braket, if you looked real close you could see where the water like touch the back part of the braket for the trailing 12" and about 6" wide, not much lift.
Problem is, I'd much rather fish around a bracket on a 31' Jupiter than any euro!
