the racing derivates like all the pogos leave aside please... benetaus, jeanneus, bavaris, hanses and that kind of breed is what i am talking about...
Sorry, I did not saw this post and that's why I did not understood well the next one
Yes, the cruisers that are designed to reach planing speed are not many but several performance cruisers are: All the JPK, Archambault, all the Pogo cruisers, Cigale and many more but you are right pointing out that is not the case with Beneteaus or the typical mass production cruiser or even the typical mass production performance cruiser.
But I guess that by now You have already understood what I am trying to say: The chines on Benetau also serve to increase boat stiffness at the best upwind angle and make sailing easier but they are not there to facilitate planing and are not designed the same way the ones used on a planing boat are.
Chines, If well designed, on a cruising boat or in a racing boat can increase stiffness and make sailing easier but the similitude stops there. The way a hull is designed and the way chines are used is not the same on a boat designed to plan and on a cruising boat that sails in displacement mode.
