The Durmstrang Ship Returns to Hogwarts

This is a moving diorama of the Durmstrang ship that brought students to Hogwarts to compete against fellow wizards from across the globe.  This is depicted in Harry Potter and the Goblet of Fire.  At first, I built the model of the ship, then I constructed the sea framework.  Initially, the latter had a ramp to lift the ship along, by way of a small handle on her keel.  However, in order to take the pictures for the contest, I changed the smooth ramp for a set of steps that I could rest the ship on at different stages during her surfacing.
