The International C-Class Catamaran Championship, (ICCCC or I4C), is a match racing sailing competition featuring the highly innovative International C-Class Catamarans, predominantly with a wingsail rather than conventional sail plan.
It is the successor event to the International Catamaran Challenge Trophy,[1] and like it, has always been colloquially known as the "little America's Cup", despite there being no actual connection to the Americas Cup. This terminology has been contested as being trademark violation against America's Cup Properties Inc, but the name was common in use long before ACPI and its trademarks.[1]
