Anatomy of an iron ship

IRON PARTS WERE USED IN THE HULLS OF WOODEN SHIPS AS EARLY AS 1675, often in the same form as the
wooden parts that they replaced. Eventually, as on the tea clipper Cutty Sark (below), iron rigging was
found to be stronger than the traditional rope. The first “ironclads” were warships whose wooden hulls
were protected by iron armor plates. Later ironclads actually had iron hulls.
The model opposite is based on the British warship HMS Warrior, launched Steel yard Iron wire stay
in 1860, the first battleship built entirely of iron. The plan of the Steel lower
iron paddlesteamer (bottom), built somewhat later, shows that this mast
vessel was a sailing ship; but it also boasted a steam propulsion Steel
plant amidships that turned two side paddlewheels. bowsprit
Early iron hulls were made from plates that were
painstakingly riveted together (as below), but by the TEA
20th century vessels began to be welded together, CLIPPER
whole sections at a time. The Second World War
“liberty ship” was one of the first of these
“production-line vessels.” Wooden Forged
