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.
Davit systems are most often used to lower an emergency lifeboat to the embarkation level to be boarded. Davits can also be used as man-overboard safety devices to retrieve personnel from the water. The lifeboat davit has falls (now made of wire, historically of manila rope) that are used to lower the lifeboat into the water.
This movement is called âscapular elevation.â It uses the muscles Trapezius and Levator Scapulae. Another way to raise your arm is to lift it completely sideways. This movement is called âabduction.â When you do this you can actually only abduct your arm until it is straight sideways. The muscles used to get here were mostly Deltoid and Supraspinatus. Lastly, you can raise your arm by moving it forward in an action called âflexion.â Like abduction, you can only flex your arm until it is straight forward. The muscles used to get here were mostly Coracobrachialis and Biceps Brachii, although there was probably also a little help from Deltoid, and Pectoralis Major.
