a large boat, with pointed bow and stern, long and narrow
A large, long rowboat, pointed at both ends to increase maneuverability, used in the 19th century by whalers
A whaleboat is a type of open boat that is relatively narrow and pointed at both ends, enabling it to move either forwards or backwards equally well. It was originally developed for whaling, and later became popular for work along beaches, since it does not need to be turned around for beaching or refloating.
