No, a ragged-bottom hull typically refers to a hull shape that has uneven or irregular surfaces, which can affect the boat's performance in the water. Planing hulls, on the other hand, are designed to lift out of the water at higher speeds, reducing drag and increasing efficiency.
That is a boat hull that does not have a keel beam or a defined chine.

Hull Is The Inside or bottom(?), and deck is the top. other than that i thinks its just called a boat. My best answer would be hull.
The Hull is considered the bottom of a boat, comes in several different forms.
The best plaining boat is one that has a flat bottom. A good plaining boat is a Boston Whaler
The hull on a boat is the body of it. It is watertight so that no water leaks in and sinks the boat.
The bottom of the boat is called the keel. Attached to and atop that is the hull, part of which is below the waterline, part above. Unless you're talking about a little ol' flat bottomed dinghy -- then the bottom is just called the bottom.
On the hull
Displacement: The weight of the water the boat displaces. Hull weight: The weight of the hull of the boat
That would be its keel.
the hull helps keep the boat stable, if there was no hull, the boat would go in different directions
