site:wikipedia.org what is the biggest boat
At 17 metres long, the Severn-class lifeboats are the largest class of UK lifeboat. A boat is a watercraft of a large range of sizes designed to float, plane, work or travel on water. Small boats are typically found on inland waterways (e.g. rivers and lakes) or in protected coastal areas. However, boats such as the whaleboat were designed for operation from a ship in an offshore environment.
