Definitions for "CAREENING"
beaching a ship, heeling her over and scraping barnacles from her bottom for faster sailing. Not a desirable job.
The careening of a sailing vessel is laying her up on a calm beach at high tide in order to expose one side or another of the ship's hull for maintenance below the water line when the tide goes out. The process could be accentuated by securing the top halyard to a fixed object like a tree or rock and pulling the mast over as far as possible. Such maintenance might include dry rot or cannon shot repair, tarring the exterior to reduce leakage or barnacle removal to increase her speed.
