David

A davit is a small crane mounted on a ship's deck, used to lower and raise boats, anchors, or cargo over the side. The word first appears in English around 1400, and most etymologists trace it to the personal name David, likely referring to a specific craftsman or inventor whose davit design became standard. The connection has never been proven, and the man himself — if he existed — left no other record.

By the 1600s, davits were standard equipment on warships and merchant vessels alike. The paired davits that swing lifeboats out over the water became the defining image of maritime safety equipment. Every painting of a sailing ship from this period shows davits along the rail, small cranes waiting for the moment they would be needed most.

The Titanic had twenty davits, each designed by the Welin Davit Company to handle multiple lifeboats in sequence. The ship carried enough davit capacity for 48 boats but sailed with only 20, a decision made by the White Star Line to keep the deck uncluttered. On the night of April 14, 1912, those davits lowered half-empty lifeboats while 1,500 people waited in the dark. The inquiry that followed made davit capacity and lifeboat provision a matter of international law.

Modern cruise ships carry gravity davits that can deploy lifeboats in minutes. The International Convention for the Safety of Life at Sea, written in direct response to the Titanic disaster, specifies davit requirements down to the kilogram. A word that may have started as one man's name now appears in the safety regulations of every maritime nation on earth.
