Air is less dense than water, so to trap air uner a boat can make it float better if it is well controlled. I hope this helped.

air bladder is present which regulates buoyancy
release air from your buoyancy vest.
Buoyancy aids contain air because it is a lightweight, readily available, and effective way to provide flotation. The air inside the buoyancy aid increases its volume while reducing its weight, helping the user stay afloat in water. Additionally, air is relatively inexpensive and does not add unnecessary bulk or weight to the buoyancy aid.
Buoyancy is useful for objects or substances that are floating or submerged in a fluid. It allows boats and submarines to float or stay afloat in water, and also helps hot air balloons and blimps to rise and stay airborne. Understanding buoyancy is important for designing structures that need to float or be submerged in fluids.
An air pocket in water is a pocket of air trapped underwater. It affects buoyancy by reducing the overall density of the object, making it more buoyant. When diving, encountering an air pocket can cause a sudden increase in buoyancy, potentially leading to a rapid ascent if not managed properly.
The force that makes things float is called buoyancy.

the buoyancy
Air pockets in water decrease the overall density of the water, causing objects to float more easily due to increased buoyancy.
Buoyancy is used by objects to float or rise in a fluid, such as water or air, due to a force acting in the opposite direction of gravity. To utilize buoyancy effectively, objects can be designed with specific shapes or materials to displace enough fluid to stay afloat. It is a fundamental principle in designing boats, submarines, and hot air balloons, among other applications.
No, they do not, they get "bouyancy" from the speed of air around the wings.
For a full explanation of how the buoyancy principle works and how it relates the helium and hot air balloons go to the related question "What is the buoyancy principle?" in the Related Questions section below.
