This is a model of a cog. It was a slow and spacey sailing ship during the Hanseatic time in the North- and East-Sea of the 14th century. It was the main vessle that sailed in convoies to be protected against attacks.
The model is partially rigged and contains NGons (BMesh). The sole part that is not are the tackles that follow the boom and the gaff.

I would say, this counts as a vehicle. Check out this competition: http://blendercontest.com/june-contest-planes-trains-and-automobiles/
