Climbing it's own waves would be no problem if it created any waves to climb. The marine industry, being as conservative as it is, took forever to get over this concept and to this day still struggles with it. Wide and narrow have their place in combination with other factors, but in the new runabouts wide is definitely the winning combination. Planing hulls use an entirely different hull form in anticipation of not only climbing up the mountain of waves they create but surfing down the other side. In this way they resemble skimming dishes with large, shallow areas with which to lift themselves up and out of the water.
Light weight is important but so is area.
The broad bottom provides a wide area for the water to make initial contact. The water is forced to change direction downward, and this imparts an upward force on the hull bottom. Most boats have considerable deadrise to soften the ride in rough water by allowing some of that lifting force to slide out to the sides when the hull is pressed into a wave. By turning down the chine flats the water is deflected at the last minute as it exits the hull, imparting some of the escaping forces to the hull. Because this water and spray are up high it does not have the force that the solid green water does down at keel level and thereby provides a smooth but effective ride.
