From the web: Assyrian Trader Colony Bronze Age terracotta boat shaped ritual vessel. This cult pot is boat shaped with an animal head at the front. Inside the vessel is a model of a temple and goddess. The deities associated with the ritual vessel were associated with trade and transportation in Ancient Mesopotamia and Summerian literature. The vessel signifies a religious river trip. - 19th century BC - Kültepe Kanesh - Museum of Anatolian Civilisations, Ankara, Turkey.
The museums speaks of a "sandal shaped" object, I think a mistake was made in the translation and used "boat" or "vessel".
