They're not necessarily designed to make a wake that disperses quicker. Much of it has to do with how a wake/wave is created by a boat. Without getting deep into a bunch of hull design theory and fluid dynamics, any boat is displacing some amount of water at all times. When under power you are displacing water, and pushing that displaced water out and away from the hull.

The weight of the displaced water is equal to the weight of the vessel. There are things you can do on any boat to change how it rides, and how/where most of the water displacement occurs. This can have the effect of creating more or less wake, but the sum of the displaced water is always going to be the same.

Wakeboats produce a large wake (duh!), but that wake is lower energy than that of a larger (heavier) boat, due to it essentially being the effect of displacement of a much lighter overall boat.

Lower energy wakes/waves will dissipate faster.

So, what you see from wake boat waves dissipating is more of a side effect of the light hull than a specific design element.
