Preparation for Launching

This diagram shows the arrangement of hull supports, called poppets, for the launch of the ship. The ship is built on building blocks and shores. Its weight is transferred to the launching cradle and poppets just before launch by wedging the ship up from the keel blocks. The poppets and launching cradle are fitted and then the wedges are knocked away. The cradle slides down greased ways, carrying the ship into the water.
