What does floatability mean?
Floatability is the noun naming the quality or property of being able to float. It is especially used when describing the behavior of a material, object, or substance at the surface of water or another liquid. A structure with good floatability resists sinking, while a material with poor floatability may become submerged. The term appears in technical discussions of engineering, ship design, materials science, environmental science, and the behavior of oils or debris in water, although it is also found in general descriptions of physical characteristics. Floatability is related to buoyancy, but the words emphasize different aspects: floatability focuses on the capacity to remain afloat, while buoyancy commonly refers more broadly to the upward force or tendency associated with floating. The word is uncommon in everyday speech, where “the ability to float” is often clearer. It is nevertheless useful in formal writing when the property itself needs a concise technical name.

- The quality or property of being able to float, especially at the surface of a liquid.
"Engineers tested the wood's floatability before using it to construct the floating platform."
"The low density of the material gives it excellent floatability in freshwater."
"A series of tests revealed considerable differences in the floatability of the two samples."
Usually used as an uncountable noun; the plural is rare and appears mainly when different instances of the property are being compared.
"The researchers compared the floatabilities of the natural and synthetic materials."
Floatability is the difference between something that stays at the surface and something that merely survives the plunge.

Where does floatability come from?
Floatability is an English formation built on the Germanic root float with the English suffix -ability, through the related adjectival form floatable. The base word descends through Middle English from Old English, ultimately reflecting a Germanic origin. Related English formations such as floatable, flotation, and floating preserve the same lexical base, with flotation developing separately through the suffix -ation.
How floatability is actually used
Floatability is a relatively uncommon and mainly formal or technical noun, particularly in engineering, materials science, environmental science, and discussions of shipping. Ordinary language usually uses “buoyancy” or a more direct phrase such as “the ability to float.”
Easily confused with floatability
Floatability is the capacity of a material or object to float, whereas flotation is the process of floating or of separating materials by means of floating.
