Ask any scientist about fluid dynamics and if they are honest with you, they'll admit how complex the subject really is. This is chiefly because mathmatically calculating turbulance is very complex. There are two types of flow in fluid dynamics that we must understand to see how the concept pertains to drift boat hull design. These are laminar flow and turbulent flow.
Turn on a water faucet slowly and watch as the water leaves the tap. As it first leaves the tap it is smooth and undisturbed. The flow at that point is laminar and drag is minimal. Laminar flow is very fragile and can change quickly. Turn the tap on more and watch as the water as it speeds up. The water is disturbed by air and surface texture and becomes less smooth rippled with eddies, swirling, and random motions. At that point the water is in a turbulent flow. Laminar flow conditions are what you look for in hull design because drag is considerably less than with turbulent flow.
