Why do boats glide in shallow water?

Boats glide in shallow water due to the reduced resistance from the water compared to deeper areas. In shallow water, the hull of the boat can create a larger wave, allowing it to "plane" on the surface and maintain speed with less effort. Additionally, the bottom of the boat can interact with the bottom substrate, providing lift and reducing drag. However, the specific design of the boat's hull also plays a crucial role in its ability to glide efficiently in shallow conditions.
