Many displacement hulls have chines. Many boats built of plywood, especially home built, or of steel have hard chines because it is easier to build them this way. It is difficult to "torture" or bend in two directions at once plywood or steel. A hard chine hull only needs to bend each panel in one direction. Any boat with a flat bottom has hard chines by definition. Planing hulls use chines to help increase the planing forces, not because of construction.
a displacement hull is like a canoe's hull... it displaces water
Planning hull
Displacement: The weight of the water the boat displaces. Hull weight: The weight of the hull of the boat
Displacement hull.
Displacement, Semi Displacement and planing
Displacement hull.
A displacement hull is an efficient, non planing hull that moves through the water at 1.34 times the square root of the waterline length (LWL). This is not "directly" related to the designed displacement of the boat, that is, usually the weight of the boat, all additional gear, fuel, water, crew, cargo and everything else on board. Besides being efficient a displacement hull is usually more capable in rough weather and requires a relatively small inexpensive engine.
Displacement hull.
A displacement hull always displaces an amount of water equal to the weight of the boat. A planing hull at a certain speed, will begin PLANING and rise partly out of the water, forced up by its v shaped hull, and only be displacing an amount of water equal to partial weight of the boat. A large ship, a tugboat, a barge, or a sailboat are displacement hulls. A speedboat or a jetski are planing hulls.
a hull of a boat that pushes through the water, this is the ordinary kind. Like most boats and ships. A planing hull is the other kind, where it skims along the top of the water, like a jet boat

its very buoyant and rides smoothly through the water.
