Careening a sailing vessel means to beach it at high tide in order, usually, to expose one side or another of the ship's hull for maintenance below the water line when the tide goes out. A ship /ʃɪp/ is a large vessel that floats on water Ships are generally distinguished from Boats based on size To beach a vessel is to lay ashore or ground it This is more usual with small flat-bottomed boats Characteristics A tide is a repeated cycle of sea level changes in the following stages Over several hours the water rises or advances up a beach in the flood A hull is the body of a Ship or Boat. It is a central concept in floating vessels as it provides the Buoyancy that keeps the vessel from sinking Small boats, as in the photo, need not always be laid over.
The process could be assisted by securing a top halyard to a fixed object such as a tree or rock to pull the mast over as far as possible. In Sailing, a halyard or halliard is a line ( Rope) that is used to hoist (pull up a Sail, a Flag or a yard. The mast of a sailing ship is a tall vertical or near vertical Spar, or arrangement of Spars which supports the Sails Large ships have several masts Maintenance might include repairing damage caused by dry rot or cannon shot, tarring the exterior to reduce leakage, or removing biofouling organisms such as barnacles to increase the ship's speed. In the field of construction dry rot refers to the decay of timber in buildings and other wooden structures by certain Fungi. | NOTE Throughout this article "cannon" is used as BOTH the || singular and plural Tar is a viscous black Liquid derived from the Destructive distillation of organic matter Biofouling or biological fouling is the undesirable accumulation of Microorganisms Plants Algae and Animals on submerged structures A barnacle is a type of Arthropod belonging to infraclass Cirripedia in the subphylum Crustacea, and is hence distantly related to A particularly well-protected area might be called "Careening Bay" to the locals. Pirates would often careen their ships because they had no access to dry docks. Piracy is Robbery committed at sea or sometimes on shore without a commission from a sovereign Nation (as distinct from Privateering A drydock is a narrow basin or vessel that can be flooded to allow a load to be floated in then drained to allow that load to come to rest on a dry platform A secluded bay would suffice and this is where they would careen their ships for necessary repairs and/or hull cleaning. This would make the ships faster, and therefore more capable of overtaking prize vessels.
At one extreme of the spectrum was the ancient practice of beaching a ship on a shingle beach with the goal of using wave action and the shingle to scour the hull. A shingle beach is a Beach which is armoured with Pebbles or small to medium sized cobbles
Robert Louis Stevenson's Treasure Island contains a reference to the practice: the Hispaniola is purposely beached on the island. Robert Louis Balfour Stevenson (13 November 1850–3 December 1894 was a Scottish novelist poet and travel writer, and a representative of Neo-romanticism in Treasure Island is an adventure Novel by author Robert Louis Stevenson, narrating a tale of "pirates and buried gold" Although the purpose of this is to avoid the uncertainties of anchoring her with nobody aboard, that a piratical crew member would be quick with the suggestion—and the means of freeing the ship later—shows his familiarity with the practice.
