Treenailed boat The treenailed boat is a boat model used in Northern Europe, usually associated with Vikings but should perhaps be ascribed to Pomeranian groups. The shape and construction coincides with the sewn boats, but instead of ropes, it is assembled with wooden treenails.
Jolly boat The jolly boat was a type of ship's boat in use during the 18th and 19th centuries. The origins of the name is the subject of debate, but it was by the 18th century one of a number of ship's boats, and was used mainly to ferry personnel to and from the ship, or for other small scale activities. The design continued to evolve throughout its period in service.
