Buoyancy tersely: Buoyancy = weight of displaced fluid. Archimedes' principle does not consider the surface tension (capillarity) acting on the body, but this additional force modifies only the amount of fluid displaced and the spatial distribution of the displacement, so the principle that "Buoyancy = weight of displaced fluid" remains valid. The weight of the displaced fluid is directly proportional to the volume of the displaced fluid (if the surrounding fluid is of uniform density). In simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or
Buoyancy aid at the sides of the garment, resulting in a garment that has more overall coverage Buoyancy aids for sea and long distance touring often feature several large pockets for storing essential equipment, and many also accommodate hydration packs. They have to be comfortable to wear whilst paddling for long distances, and so typically have very low cut sides to allow the arms free movement. More recently they are being designed more and more like whitewater vests, with low cut fronts to allow the paddler to lean forward easily. Whitewater buoyancy aids are designed to provide enough buoyancy in fast whitewater
