In Britain, it means diddly. It means you're a male, presumably respectable. If you have no other title, then the overly-British will put esq. after your name on an envelope, etc. In America, I believe it's sometimes used after a lawyer's surname. However, I don't see it used much by U.S. lawyers.
This type was used on the Lifeboats of the RMS Titanic. Each arm must be rotated out manually; uses manila rope falls. Goose-neck shape to the arm that is swung out. Mechanical (obsolete) â This type is like the radial davit, but both arms are moved out at the same time using a screw system; uses manila rope falls.
The Titanic was originally fitted with 16 davits, each with 4 lifeboats, which was more than enough for everyone on board. The White Star Line (Ismay) ordered the removal of three lifeboats per davit, leaving only 16 lifeboats, as the line claimed the full 64 lifeboats made the ship look bad.
