Ever wonder why amphoras are shaped they way they are?
It's so multiple layers could be packed into the hold of a ship. Dunnage and packing material such as straw would fill the gaps between the amphoras, locking them into place. This model of an ancient ship's hold is in the Maritime Museum in northern Sardinia.
 
 

This is the Surface Support Vessel CAROLYN CHOUEST, with the US Navy Submarine NR-1 on her port hip. The gray ship in the left background is the submarine tender USS SIMON LAKE. The CHOUEST is a dynamic positioning vessel; the vessel's omni-directional thrusters are controlled by the ship's navigation computers, which collect positioning information from GPS. DP vessels like the CHOUEST can hold precise positions in the open sea without mooring systems.

This is the control space of the submarine NR-1. Note the prone figure behind the helmsman and sonarman: that is NR-1 Officer-In-Charge Chas Richard, and that is his bed for the entire deployment.

Scholars from several institutions and many disparate disciplines collaborated on the Skerki Project. This picture by no means portrays them all, as many had already departed for shore.
