Overview
Sometimes the whole support is called a "cradle", sometimes each section of this support is called a cradle. The cradle can be standing on the dock floor or it can be equipped with wheels so that the ship standing upon it can be transported from the dry docking installation to a parking area. For smaller boats, the cradle is equipped with rubber-tyred wheels, for larger and more heavy ships, the cradle is equipped with steel rail wheels.
