A clam boat is a vessel specifically designed for harvesting clams from the ocean floor. However, this term may not always be used depending on the region or country. In some areas, a clam boat is referred to as a clamming boat or a clamming skiff. In the UK, it may be called a cockle boat. Other possible synonyms include dredger, rake boat, tong boat, and sloop. Each term may vary depending on the region, specific type of boat, or method of harvesting used. However, the fundamental purpose of the boat remains the same - to collect fresh clams for culinary purposes.
