Abstract: A davit device (20) is arranged suspended over an associated boat (123) onboard a ship (25) or similar vessel. Horizontally, telescopically displaceable davit arms (121, 121) can move the boat (123) from a parking position to a launching position, and vice versa, while a hoisting device (122) can move the boat (23, 123) vertically. In that the hoisting device (122) is secure to the radially innermost, axially extendable telescope part (121a, 121a) of the davit arms (121,121), the vertical and horizontal movements can be carried out independently, in a controlled way.
