Heave down refers to a nautical term primarily used in shipbuilding and maintenance. It is the act of leaning a vessel on its side, either partially or wholly, in order to expose its hull for various operations such as cleaning, repairs, or inspection of its bottom. This process typically involves using ropes, tackles, or other mechanical means to tip the ship over onto its side.
During the heave down process, the ship is usually secured to prevent it from toppling over completely. This can be achieved by tying it to sturdy objects like wharves or using anchors to maintain stability. Once secured, the ship's hull becomes accessible for necessary maintenance tasks.
Heave down is commonly employed to address issues related to the underwater portion of a vessel's hull, such as removing marine growth like barnacles or repairing damage caused by collisions or wear and tear. It allows shipbuilders, sailors, or maintenance crew to thoroughly examine and work on the ship's bottom, which is usually submerged while the vessel is in the water.
This technique requires expertise and careful planning to ensure that the operation is executed safely and efficiently, as it involves manipulating large structures that can weigh hundreds or even thousands of tons. Heave down has been a crucial part of shipbuilding and maintenance throughout maritime history, contributing to the seaworthiness and longevity of countless vessels.
The word "heave down" has its roots in nautical terminology.
"Heave" comes from the Old English word "hebban", meaning to lift or hoist. It evolved over time, reaching Middle English as "heven". The term "heave" in the nautical context refers to the act of raising or lifting something, especially a heavy object like an anchor or a sail.
The word "down" here implies lowering. It is derived from the Old English word "dūn", meaning a lower or downward movement. It has remained largely unchanged in its meaning over the centuries.
When combined, "heave down" refers to the action of lowering or hauling down an object, typically a ship, from an upright position to a leaning one.
