bottom contours - double vs a single to double

I searched but wasnt succesful finding info to my question so I thought I would start a new topic

I was looking at picking up a hybrid type board (7’2" x 22 x 3) 5 fin boxes - it has a double concave stating about 14 inches from the nose and continues through out the board, with V through fin cluster and off the tail.  My question is how does a board with a double con- vee ride differently than a single to double bottom? Any design insight would help

thanks Jimi

double double 

no vee but, yeah
