iron clads
You're probably asking about the ironclads.The ships with metal plates on their side were introduced in the 20th century. They can take on heavier payloads and that makes the fit for merchant and warfare purposes. In warfare, they are harder to sink than the predecessors which had wooden hulls.
The first metal battleships were made during theAmerican civil war by both sides simultaneously during their battle neither ship was destroyed but the North had a wooden ships destroyed. This showed that the metal ship was to be the future of warfare.
No..Like all disasters that are man made, there are always rumors to that effect..The metal on the ships sides was unable to sustain the blow from the berg, she took water, and sank.

When Othniel Charles Marsh discovered Stegosaurus in 1877, he believed that the plates laid on Stegosaurus's sides like the shingles on a roof. That is why he called it Stegosaurus, meaning "roof lizard" in Greek. Now we know that the plates stood up vertically.
It depends on whether you are talking about regular cargo ships or warships which under sail were called "men o war". Cargo ships do not have holes in the sides but the war ships had holes, above the water line, for them to poke the cannons through. Hence you could say the "men o war" had holes in the side but not cargo or passenger ships.
Vessels made of a combination of wood and metal, called iron clads, were first sued by the two sides in the US Civil War.
The metal pendulum inside a bell is called a clapper. It strikes the sides of the bell to produce sound when the bell is rung.

They are called sides.
Throw ropes with hooks attached to ships or even castles to scale the walls or sides of the ships.
The stiffener used to strengthening the sides surface (hull) of the ship is called stringers. Without using stringers the hull shape of the ships does not formed.
