As a ship slides backward, its weight must be distributed flawlessly across the cradle supports to prevent extreme contact pressure points from denting the steel plating. As the stern finally enters the sea and begins to float while the bow remains grounded on land, the hull undergoes intense structural bending stress.

To prevent the ship's keel from failing under severe hogging or sagging forces, designers utilize classic beam formulas to monitor structural load shifts in real time. Mechanical triggers and secondary safety pins lock the vessel in place until the exact moment buoyancy takes over and heavy drag chains control its momentum.
