harpoon

A harpoon is a long spear-like instrument used in fishing to catch fish or large marine mammals such as whales. It accomplishes this task by impaling the target animal, allowing the fishermen to use a rope or chain attached to the butt of the projectile to catch the animal. A harpoon can also be used as a weapon.

History

"Manner in which Natives of the East Coast strike turtle." Near Cooktown, Australia. From Phillip Parker King's Survey. 1818.

Spearfishing with barbed poles (harpoons) was widespread in palaeolithic times.^[1] Cosquer cave in Southern France contains cave art over 16,000 years old, including drawings of seals which appear to have been harpooned.

There are references to harpoons in ancient literature; though, in most cases, the descriptions do not go into detail. An early example from the Bible in Job 41:7: Canst thou fill his skin with barbed irons? or his head with fish spears?.

The Greek historian Polybius (ca 203 BC–120 BC), in his Histories, describes hunting for swordfish by using a harpoon with a barbed and detachable head.^[2] Copper harpoons were known to the seafaring Harappans^[3] well into antiquity.^[4] Early hunters in India include the Mincopie people, aboriginal inhabitants of India's Andaman and Nicobar islands, who have used harpoons with long cords for fishing since early times.^[5]

Whaling

For over 8000 years, the two flue harpoon was the primary weapon used in whaling around the world, but it cut through the blubber when under stress. This flaw was corrected with the creation of the single flue harpoon; by removing one of the flues, the head of the harpoon was narrowed, making it easier for it to penetrate deep enough to hold fast. In the Arctic, the indigenous people used the more advanced toggling harpoon design. In the early 19th century the one flue harpoon was introduced, which reduced failed harpoonings due to the head cutting its way out of the body of the whale. In the mid-19th century, the toggling harpoon was adapted by Lewis Temple, using iron. The Temple toggle was widely used, and quickly came to dominate whaling.

Explosive harpoons

In 1870, a Norwegian man named Svend Foyn successfully patented and pioneered the exploding harpoon and gun based on Erik Eriksen's idea and design. Together with the steam-powered whale catcher, this development ushered in the modern age of commercial whaling. Euro-American whalers were now equipped to hunt faster and more powerful species, such as the rorquals. Because rorquals sank when they died, later versions of the exploding harpoon injected air into the carcass to keep it afloat.

A certain type of explosive harpoon fired from a shoulder gun, first used by American whalemen in the mid-19th century, was called a "bomb lance."

Modern developments

Modern whaling harpoon.

The modern whaling harpoon consists of a deck-mounted launcher (mostly a cannon) and a projectile which is a large harpoon connected to a thick rope. The spearhead is shaped in a manner which allows it to penetrate the thick layers of whale blubber and stick in the flesh. It has sharp spikes to prevent the harpoon from sliding out. Thus, by pulling the rope with a motor, the whalers can drag the whale back to their ship.

A recent development in harpoon technology is the hand-held speargun. Divers use the speargun for defense against dangerous marine animals. They are also used for spearing fish. Spearguns may be powered by pressurized gas or with mechanical means like springs or elastic bands.
