how does lifeboat davit arm work
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 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.
