A whaleboat is a type of open boat that was used for catching whales, or a boat of similar design that retained the name when used for a different purpose. Some whaleboats were used from whaling ships. Other whaleboats would operate from the shore. Later whaleboats usually could operate under sail or oar - American whaling crews in particular obtained better results by making their first approach to a whale under sail, then quickly unstepping the mast and using oars thereafter.
