The bulkhead, left, prevents water from entering at Lock and Dam No. 2 so work can be done on the gates to the chamber, right, Jan. 30 on the Mississippi River in Hastings, Minnesota.
Two straps, known as "hiking straps", run lengthwise along the floor from the bulkhead to the stern. These and a tiller extension allow a sailor to hang off the side for weight distribution—commonly called "hiking out". This can be crucial to keeping the boat more upright during heavy air, allowing greater speed through the water.
Today, bulk carriers make up 21 percent of the world's merchant fleets, [2] and they range in size from single-hold mini-bulk carriers to mammoth ore ships able to carry 400,000 metric tons of deadweight (DWT). A number of specialized designs exist: some can unload their own cargo, some depend on port facilities for unloading, and some even ...
The underwater protection was an internal "bulge" that consists of four longitudinal torpedo bulkheads forming a multi-layered system designed to absorb the energy from an underwater explosion equivalent to 700 pounds of TNT (1.3 GJ). The protection system was designed for the torpedo bulkheads to deform and absorb energy while several ...
The aft pressure bulkhead is the white circular component; its web-like structure led a NASA technician to attach a large model spider to it for comedic effect. The aft pressure bulkhead or rear pressure bulkhead is the rear component of the pressure seal in all aircraft that cruise in a tropopause zone in the Earth's atmosphere. [1]

A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads.It is analogous to a room within a building, and may provide watertight subdivision of the ship's hull important in retaining buoyancy if the hull is damaged.
