Apparently, Jonah boarded this kind of seaworthy cargo ship, which was able to make the long voyage from Joppa to Tarshish (likely ancient Spain). It probably had a high carved prow, near which hung a stone anchor. Passengers, rowers, and some cargo could fit on the deck, which is not shown in this model. Below deck was a hold, where more cargo would be stored and where Jonah went to sleep. The ship was made of sturdy juniper planks and had one cedar mast to support a large linen sail. Note on each side the line of long oars (probably of oak from Bashan). Now imagine the ship at sea and threatened by a violent storm.
