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. 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. 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 drydocks.
A secluded bay would suffice for necessary repairs and/or hull cleaning, and such little “safe havens” could be found throughout the islands in the Caribbean and nearly around the world. One group of islands, Tres Marias, became popular when Francis Drake had sailed there in 1579 and quickly became a place for piracy . Careening would make the ships faster, and therefore more capable of overtaking prize vessels.
One exotic method 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.
Robert Louis Stevenson's Treasure Island contains a reference to the practice: the Hispaniola is purposely beached on the island. 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.
