What does cobby mean?
Cobby is an informal English adjective describing someone or something as stout, sturdy, and thickset. It is used most often of people and animals — a cobby pony has a compact, muscular body on relatively short legs — but it also has a long-standing place in nautical language, where a cobby boat means one that is strongly built and dependable in rough seas. The word derives from cob, a term for both a stocky type of horse and a rounded lump or loaf, combined with the familiar adjectival suffix -y. Its connotation is almost always positive: to call an animal or vessel cobby is to praise its strength, substance, and reliability rather than its elegance. Though never a formal word, it remains current among horse enthusiasts and traditional sailors, particularly in Britain, and offers a vivid, affectionate way to celebrate solid, unpretentious sturdiness over showy refinement.
Stout and sturdy in build; short and thickset.
"The cobby draft cross pulled the cart effortlessly up the hill."
(Of a boat) Strongly built; capable of handling rough seas.
"Her cobby little ketch had seen forty years of North Sea weather."
This nautical sense is chiefly British and traditional among working-boat sailors.
In nautical circles, a "cobby" boat isn't clumsy — it's the tough, seaworthy hull you want when the weather turns foul.

Etymology of cobby
Cobby derives from the noun cob, an old English word for a stout, short-legged type of horse, combined with the adjectival suffix -y. The root cob itself is of uncertain deeper origin but has long denoted rounded, lumpy things — hence cobblestone and cob of corn — which fits the word's sense of compact solidity. The adjective arose in British dialect and colloquial speech, later extending to describe seaworthy, strongly built boats.
How cobby is actually used
"Cobby" is informal and somewhat old-fashioned or regional in tone, more likely to be heard among horse fanciers, farmers, and sailors than in formal writing. It carries an affectionate, approving connotation — solidity and strength are being praised, not mocked.
