lifeboat

watercraft especially built for rescue missions. There are two types, the relatively simple versions carried on board ships and the larger, more complex craft based on shore. Modern shore-based lifeboats are generally about 40-50 feet (12-15 metres) long and are designed to stay afloat under severe sea conditions.
