A hover craft service bay, 5.00 m wide, 7.13 m deep and 5.01 m tall. A plated floor carries four columns and an overhead frame with light rails and a lit rear header. Hazard guards line both flanks, and a rear tool board with four shelves and a hose reel completes the working end. A scissor lift deck with edge hazard pads and glowing end strips sits at 1.15 m; the deck, its scissor legs and pads form one node named "lift-deck" with a pivot at [0, 1.15, 0]. The "cradle-saddle" port sits at that same point facing +Y, so a craft with a "cradle-belly" port rests exactly on the deck. The bay stands on its own floor slab at y=0. Static geometry; no rig, collision or navigation data.
